10.9 GB 'hotfix' patch is out today on the Gamepass version.
I've played it for 30 hours or so, taking my time to do every obvious quest and hoovering up loot (which does become a bit pointless after a certain point)
The main thing I would say is that after the prologue, and on the first part of the game you land outside a town called 'Fairfield'. Track down an NPC called Huell Chaudry and do his quest almost immediately, it'll give you a very useful double jump skill which is pretty handy for exploring/climbing. It's not far from the settlement anyway.
As for my previous stealth issue - as far as I could tell you can't get a Sniper rifle until you complete the first 'World' and there's a companion who buffs stealth that you can't get until the second World unlocks either, this, along with investing lots in sneak has made my stealth person pretty good now at taking out enemies from a distance in one shot, but it took a while to get there.
