What "more sim" gaming than me are you doing exactly? Be specific.
I play Torchbearer 2e. When PCs get injured, or sick, their performance of tasks is impeded. When they get exhausted, they are closer to death (without that being on a separate track from the damage track). When they use their skills/abilities, they get better at them. When they lose their gear, they find it harder to perform tasks they require tools or other equipment.
There are other aspects too, but those are some of them.
I play Burning Wheel. In combat, positioning matters and characters can wrongfoot one another. Blocking and parrying of blows matters. Injuries set back those who suffer them; and when someone is (say) struck on the hand or arm, there is a chance for them to drop what they're holding. Armour also gets degraded by combat. And resolution in combat is simultaneous, not "stop motion".
In BW, characters can improve their abilities through training and/or practice. As well as by using them.
In both TB2e and BW, using magic can exhaust a practitioner - that is not necessarily more "realistic", but it does seem closer to the idea that the practitioner is channelling and invoking powerful and dangerous energies.
I play Classic Traveller. Injuries set back the performance of those who suffer them. Characters can improve via instruction. PCs tend to have an age commensurate with their prior experience and hence their training and ability. Resolution in combat is simultaneous rather than "stop motion". Characters moving about in vacc suits have to take care to avoid tears, snags, etc that might breach their suit.
In the past I've played RM (a lot), RQ and other BRP games.
These are the sorts of reductions in abstraction that you say you prefer. I don't doubt your preference. But to me it seems that you're not playing RPGs that would tend to satisfy it.
