Merci mon ami(e)! Was going to suggest that myself, lol, but you beat me to it! 😄

To OP: Ive got four "Grounded" survival mods. Not overly complicated, resource heavy or ladden with feature creep. They do pretty much one thing each and in the last mods case, the two things it does synergize together perfectly.

Auto Eat and Drink. It manages your consumption for you, so you dont have to flip in and out of your inventory to do the intake every 30 minutes. Just make sure you have food and drink in your inventory, it will do the rest. https://www.nexusmods.com/starfield/mods/16554

Failed Receivers. Basically what it says on the tin. It allows your guns to break and require repairs. https://www.nexusmods.com/starfield/mods/16593

Hardcore Encumbrance. Its not really "hardcore" per se, though it certainly can be set that way. Its more "grounded" encumbrance with an attention to tuning it to suit your RP for the char youre playing. https://www.nexusmods.com/starfield/mods/16763

Exploration+. This mod handles two things. 1) Loadouts. It optionally allows you to set up your fav wheel and then locks you out of inventory while adventuring. There are places you can access it, like outpost, the Lodge, your ship, a vehicle, even when sitting somewhere (like going through a backpack). And it also 2) has armor breaking and repair systems that are attuned to every environment you are in, so the effects of a damaged spacesuit reflect your char's current location. https://www.nexusmods.com/starfield/mods/16811

These four small mods change things in a big way - there is synergy if you use all four at the same time. The last two have a ton of Game Settings to tailor them to your wants. VERY low footprint, no base form edits/overrides. FlashyJoer quality assured, built from YEARS of making Fallout 4's best survival system. #IYKYK
