Second thoughts from oncycle placement?

So I signed an offer at a MM/UMM fund this year on-cycle. Just given interview dynamics, this was the only fund I interviewed at (started on first night and accepted an exploding offer on the spot).

Now, I’m having some 2nd thoughts on where I landed. It’s a good fund but it’s no MF, and their general expertise area isn’t exactly what I want to do (they’re historically strongest in a few industries that I’m not as experienced/interested in).

Think it’s also just hard now when I get HH pings for off cycle interviews at funds I would love to be at, see where my fellow analysts placed, or read stuff on here about how you can only get _ exit opp or go into HBS from whatever group of funds.

Any tips on this? Not really considering reneging because I know that’s insane, just curious how everyone deals with potential regrets given that we’re making life altering decisions on no sleep with no time to consider our options. I feel like I’m happy enough overall, just a little bit of self doubt whether I played my cards right or if I should’ve done things differently
