VOO
Vanguard S&P 500 ETF
stock NYSE ETF

But VOO is proven and reliable, consistency and patience are keys, time will do the rest.

I think I will purchase VTV on a long-term basis.
Although I also like SCHD, I am interested in getting ETFs with less dividend focus for tax purposes.
I have VTI/VOO on a long-term basis, too.

if i was just starting out, id open a roth and buy VOO. I would do that till I hit the magic number 100k.

Invest $8000 in VOO. $2000 in QQQ. And don't touch it for at least 3-5 years. 
This is the long game. You're not playing scratch off's at the gas station.

This is excellent, thank you so much, you've given me a lot to think about!
You'll be pleased to know I just increased my monthly contribution to the Roth IRA. I'll need to make a small deposit at the end of this year to catch up to $7500, but am otherwise good-to-go reaching the yearly max moving forward :)
Re: home ownership, I will absolutely be looking outside of the area! Unless I win the lottery or the real estate market drops out like it's 2008, there's absolutely no chance of buying local. I do have a couple smaller cities/areas I like in CA and OR to check out again when I get closer to that point, I just honestly don't know if I can even get there.
In your experience and given I'm looking at retirement in about 20 years (if all goes well) ... do you think there's any benefit at also adding in a fund/ETF that tracks S&P500 specifically? That's also a common recommendation for "dump a chunk in and leave it alone until retirement". VOO seems to be the most popular as an ETF, with FXAIX/VFIAX as mutual funds.

Why not value and momentum? I'm in VOO, AVUV, FMTM, SGRT, AVDE, and AVEM.

That is true, as my horizon is so long, tech might fall off by then.
However, wouldn’t it be fine to rotate out of tech at that point and put it in VOO?

You should probably stick to reading other people’s posts and investing in index funds like VOO. Looking at your trades you’re going to drive yourself insane and poor.

VOO is kind of the Vanguard standard for S&P 500 index funds.

You could easily live better than most with buy and hold VOO and 2mil. Take on a bit more risk(ie slightly higher beta indexes not even options) and you are set for life.

Three questions:
1. Do you have access to the U.S. stock market?
2. How old are you?
3. What would you consider a comfortable amount to retire with?
I’m not a financial advisor, but if you’re just looking for a general answer, I’d say VOO. The right investment really depends on your answers to those three questions.
For some inspiration, check out the Reddit communities **r/RaceTo1M**, **r/RaceTo5M**, and **r/RaceTo10M**. They’re great places to see how others are building wealth. Then ask yourself where you’d like to be 10–20 years from now and build a plan around that.

He needs to buy SPY/VOO and have a life

I literally just started too! 😅 I went with VOO + QQQM and I'm planning to DCA monthly. Still learning as I go, so reading threads like this has been really helpful.
Open to advice from more experienced investors, but I'm trying to keep it simple and stay consistent.

VOO is a decent representative of the board US market.
The others are thematic ETF's and neither is a rational investing. It's only popular now because of recency bias.

You are buying tech stocks at their highs at the same time hedge funds are dumping them. Your choice is hold for as long as it takes, or sell for a loss.
Since this is investing for beginners, I would say stop buying individual stocks and buy index funds like VOO in the future.

I put my dividend funds like SCHD in my regular taxable account, and buy stuff like SPMO, QQQ, FSELX and VOO in my Roth

Respectfully disagree. I'd do a 65/35 split, VOO/VGT. Maybe even split that VOO 50/50 with VOOG to boost returns a little.
Of course, it is a little less 'set and forget' that way.

For the average person, this is spot on.
I would like to add:
1) when investing into the roth, for the love of god don't let the money sit in the money market account. That's why OP said put it in VT. Money market account is pretty fancy way for saying HYSA, so make sure to move it to an index fund (VTI/VT/VOO/etc).
2) if you're young enough, check what your 401k money is going to. Usually they set it up automatically to deposit into a lifecycle fund depending on when your projected retirement date is. I would look into the breakdown of that lifecycle fund and maybe consider switching to a stock fund that tracks the S+P. At a young age, you don't really need the diversification (bonds) yet.

Dropping in to see if you stuck with the plan. VT has outperformed VOO basically since you posted this.

Shoot for 10 to 20% based up your free income. If you can do more. Do more. As for picks your 1st should be VTI or a similar fund through Schwab or Fidelity.
In your ROTH you can invest $7500 annually or $625 a month 26% of your monthly income. More etfs can be included, but VTI is your growth engine.
If you add a second. Look at SCHD to partner with VTI. This provides a solid growth yield and income through dividends. It also give some downside protection. As you grow your account watch out for fund overlap. Example if you buy VTI, no need to buy VOO, it's inside VTI.
Let your Roth grow to provide retirement and enjoy your brokerage account and stock picks.
