That's solid advice. I'd add though - the sleep requirement thing is way more annoying than hunger imo. You can manage food by just looting corpses and cooking stuff as you go, but if you're doing a roleplay playthrough where you're actually exploring dungeons and doing quests, getting fatigued every couple hours breaks the flow hard. That's the one setting I'd actually tweak down.
Also don't sleep on (lol) the Campfire mod or similar - not because it makes Survival easier, but because vanilla camping is basically nonexistent. Being able to actually set up a bedroll and cook food at a campsite makes the whole survival loop feel less like a UI chore and more like actual survival. It's immersion-positive, not immersion-negative.
And yeah, avoid teleportation stuff, but fast travel with consequences mods are actually fine - the ones where you arrive tired or hungry or whatever. Those keep the stakes without forcing you to literally walk from Whiterun to Solstheim every time. That's tedium, not immersion.
What build are you thinking? Because Survival changes the calculus pretty hard depending on whether you're doing melee vs. magic vs. stealth. A pure mage with Mage Armor perks can actually survive rough conditions better than you'd expect, for instance.
