Okay, so first a disclaimer. The Character Origins UA is a year and a half old at this point. I would not consider it complete or up to date, and fully expect there to be changes in the final release. So don't plan too hard on anything from it.Hey, here's a Monk question: what's a good choice for your level 1 feat? I've found myself defaulting to Magic Initiate with a lot of other One D&D builds I've been doing, but I feel like Cantrips don't work well with the Monk's action economy. Can't take any of the Fighting Style feats because of the lack of the class feature. Lucky? Savage Attacker? Tough?
That said, if you just want a generic combat upgrade, you've got a few choices. Alert, Lucky, and Tough are broadly useful for just about anyone. With Alert, even if you don't want to go early in the turn order, remember that you can swap with a willing ally. Being able to supply an early action might let your party's tank get into position or your Wizard friend Fireball the enemy before they scatter. Savage Attacker isn't great, both because it's weak and because it only works with weapon attacks, but again see the disclaimer.
If you want non-combat upgrades you can always pick up more proficiencies with Crafter, Musician, or Skilled. Nothing wrong with having more skills or tools available.
