Hey Jacobi,
Others will probably have lots to say, but I want to contribute a piece of advice to read JLCollins' Stock Series. Currently has 34 entries (and counting?), but I just read through it a few weeks ago and it lays a great foundation for investing advice. JLCollins' whole shpiel is called "the simple path to wealth", so if you are interested in an asset allocation that is "dead simple", his is the strategy for you.
I also give out the JLCollins link to newbies. It is a great site, and if the OP has not read it, they really should. It's fantastic.
But - there are criticisms of his informatino. Overall, the concepts are excellent and well explained, but just because there is a lot of great stuff, does not mean he is some sort of god who should be followed without question.
Vanguard papers have shown that a 30% allocation to international has given the same long term return with lower risk. Diversification is the only free lunch in investing. JLCollins somehow thinks you should "buy the whole market" but has decided the market is his own country and not the whole world. Sure, many will show that in the last 10 years international has lagged the US, but if recency bias is your thing then you should pick the best recently preforming asset class instead of VTSAX too.
Extremely few people can psychologically tolerate seeing say a million dollar portfolio that has taken 15 years of sacrifice halve steadily over a year or two and not know when it will stop bleeding or if it going to take 10-20 years ro recover, and they will often freak out and sell some or all when it is down. It is human nature to have loss aversion.
His site has great info, but don't just blindly do what he says. Learn the concepts and apply them yourself.
Target Retirement funds are fantastic. It is also a "simple path" with one fund, but they are more diversified and they do all the work for you. Just make sure the fund picked is based on required AA and not just on age.
