New guy Q - advice

I’m sure this has been asked but I’ll ask anyway. I’m new to PC gaming and want to play games such as KCD2, RDR2, and Starfield on a handheld format, without it struggling or playing on the lowest settings. I also have a PC and am sort of new to Steam and am using vortex to install and run nexus mods.

Ideally I would play the steam based games with those mods, and bonus points if the save points also transfer.

The portable nature of a handheld seems super rad, and occasionally docking it to a tv is also pretty sweet. I understand that a Steam deck might not cut I performance-wise, but am trying to avoid some $3k monster.

What do you guys recommend?
