One thing I'd recommend, and do myself, is diversify a bit just to be safe now that you have sufficient funds to do so (and you have enough funds that you need some protection in what may be a wild market very soon). That to me means different asset classes and different geographic locations (different states, different types of investments), whatever you decide.
If you want passive, you can invest in syndications and mostly passive RE options like manufactured home parks, self-storage, multi-fam, etc. Also, I'm getting upwards of 5% on short term TBills right now which make up a small portion of my portfolio for safety and a decent, passive return. Self-storage is great if you can find a deal, that's tough right now. Industrial outdoor storage is great as well, again, if you can find a lot that pencils.
Personally, I like states that are growing. From there, I diversify my asset class and try to be in several growing/in-demand states.
All the best! It's a good problem to have for sure
