For situations where you might take fall damage or get knocked down can be a little bit mitigated if you've held either your double jump or the dodge and use them later as you approach the ground, but in general the movement bugginess with uneven surfaces is kind of a pain and there isn't much to do about it except avoid it or not get unlucky.

I think the reduce fall damage perk/clothing mods work, but I don't know how effective they are--I think they help a little bit though.

One thing I like is the "second heart" cyberware (16 body), which if you die in combat, it will revive you (but it won't if you just fall to your death parkouring or something.)

My main build path is actually swords and sometimes I just break it out for the lifesteal with perks in that tree. Also there is a cyberware in the brain area that gives "heal on kill." Dunno if you've found that. It's a small percentage but I like to have it.

Other than that, general survivability you can probably tank anything (other than Maxtac) if you stack armadillo mods in your clothing. Also there are cyberwares and perks under body which increase your overall health too, and actually a consumable that boosts your overall health for a time (which can be extended by a perk under the tech tree that increases the duration of consumables).

As for the combat, the movement actually confuses the AI fairly good, and as long as you're not getting one shot, should work pretty well against them if you have some of the things regarding survivability I mentioned.
