FWRG
First Watch Restaurant Group, Inc. Common Stock
stock NASDAQ

So..
£45k invested. 95% of it in VWRP, the rest in VUAG. Got into S&S ISA's a year or so ago, before that was very ignorant and spent years building up a significant amount of money in cash ISA's.
One such cash ISA is about to mature and has another £66k in. I have a couple of other cash ISA's with more than enough emergency money, so the £66k is fully at my disposal to lock away for 10-15 years. My thoughts are lump sum into VWRP (after looking into lump sum vs PCA apparently the research shows lump sum wins the majority of the time?), maybe I would look at a certain percentage of it into something like FWRG. I have a SIPP which I am planning to dump about £40k of other funds in and get the tax relief on, so with this maturing £66k I want to keep it inside the ISA wrapper.
My other concerns are, AI bubble collapsing the market, the government changing the rules so that once I transition the money from a cash ISA to a S&S ISA I can no longer transfer it back into a cash ISA for the security and finally as mentioned which ETF to purchase or split the £66k between.
I'm not into single stock picks, although I am slightly interested in possible big company IPO's (for example I hear Anthropic at some point?) and taking advantage of the initial pump similar to SpaceX, although I probably won't do this just being cautious by nature.
Any advice from seasoned investors is greatly appreciated.
