what would a ttrpg that prioritizes roleplay and actually functions as such look like? i've played a few that claim to be "rp forward" and every time the mechanics meant to facilitate roleplay ended up impeding it - and meanwhile i've had perfectly rewarding rp experiences in crunchier systems with no mechanical social encounter support at all. is there really a way to build rp into a system that works, or is it just a unicorn idea?
"Proiritising roleplaying" doesn't mean anything – it's a piece of vacuous marketing text targeted at people who've constructed their identity politics upon arguing about the correct way to pretend to be an elf.
The basic problem is that the term "roleplaying" is, itself, not well defined; in practice, it means whatever the person trying to sell you something wants it to mean. Here, for example, by invoking the presence or absence of "mechanical social encounter support" as the distinguishing feature of self-styled "RP forward" systems, you seem to be implicitly defining "roleplaying" to mean "set-piece encounters in which a player character attempts to persuade an NPC to do something for them without resorting to violence". Is this justified? Is playing out the process of hitting each other with sticks not "roleplaying"? Why not?
What most people mean when they toss the term "roleplaying" around in the context of tabletop games is something in the vicinity of "roleplaying is when we do things I'm interested in doing, and not-roleplaying is when we do things I'm not interested in doing". As all game rules are unavoidably opinionated about what player characters ought to spend their time doing – indeed, arguably this is the only thing that rules can meaningfully express opinions about! – the question of "does this system 'prioritise roleplaying'?" is typically reducible to "does this system agree with me about what kind of game I'm playing?". Games are then sorted into "priorities roleplaying" and "does not prioritise roleplaying" based on which side of the answer to that question they fall on for the person doing the sorting.
This is the ultimate root of a lot of this "the best sessions I ever had never touched the rules at all" stuff. For a variety of reasons, many people have genuinely never experienced playing a tabletop RPG whose rules agree with them about what sort of experience of play they ought to be having, and in some cases they can't even imagine what that would look like. If you and the system you're using disagree so badly about what kind of game you're playing that "engaging with the rules" and "engaging with my desired experience of play" are mutually exclusive activities, it's not surprising that ignoring the rules entirely would be your best play.
In this light, your question of "what would a system that really prioritises roleplaying look like?" translates to "what would a system that actually agrees with me about what kind of game I'm playing look like?", and that's not a question I can answer unless you're willing and able to get a lot more rigorous about what you mean when you say "roleplaying".
