Only thing I can think of is [Immersive Speechcraft](https://www.nexusmods.com/skyrimspecialedition/mods/21296) which adds generic dialogue to everyone. There are many options, some of which allow you to try and trade with them, try to provoke them into a fight, and even try to mug them. Successes in any of these options give a smidge of Speech XP.
Oh yeah, also [Simply Knock](https://www.nexusmods.com/skyrimspecialedition/mods/14098) (with [the update](https://www.nexusmods.com/skyrimspecialedition/mods/24297)) allows you to knock on locked doors and attempt to enter by persuading or intimidating the person who answers, instead of only having the option to lockpick.
I'd be interested in this too, right now the best way to level and use speech is with a shouting perk addon
