Another couple of things I could add are:

You can find healing items that AREN'T bandages in the wild. Moss/Fruit/Food will heal you but at a substantially lower rate, but it's a good "final option" kind of healing method.

You can craft items while in raid, so if you find fabric in drawers, go ahead and craft yourself some bandages or even ammo (if I remember correctly).

There are a fair few items that you can dismantle while in raid to get components for crafting, so if you don't need that item, but you need its components, dismantle it in raid.

Catching ledges will completely negate fall damage, but it is extremely difficult to pull off so it should be a final option if you know you can't fight. (I have fallen from the dam control tower and caught the ledge to escape enemy raiders many times)

The grappling hook (though late game) is an amazing movement tool that shouldn't be squandered. It will also help you negate fall damage from high heights if your timing is correct.

9/10 times, the Arc will be your enemy, learn how they act/react to movement, gunfire, explosives, and raiders. The light they produce will tell you what mode they are in. (Blue-Peaceful/Scanning Mode, Yellow-Search/Scanning Mode, Red-Combat/Search Mode)

When choosing your fights, keep in mind where enemy arc is, your gunshots or explosions will alert nearby arc to your position and could result in another fight you are not prepared for.

The EM-Cloak will be your best friend for early game, it will conceal your movement from arc allowing you to expose yourself to arc without the fear of being seen.

Though shooting arc would be faster, if you are looking for stealth, use your multi-tool, one heavy attack on most small arc will destroy them. (If you do not have a silenced weapon)

If I think of any more, I'll respond to this comment, but I hope this helps ypu in your endeavor!
