If you're down to try new systems you can pick up a Fujifilm xe2 for about 250$, plus a good prime for another 250$, then shoot jpeg + raw and play with Fuji's built in film sims and in camera raw conversion settings to get remarkably film like photos.

It's a whole thing in the Fuji world, see http://fujixweekly.com/

I'm not sure if the xe2 is compatible but you can also edit "on-computer" by having the camera plugged in and using its on camera raw conversion but with the UI on your computer: https://fujifilm-x.com/global/support/download/software/x-ra...

For system agnostic, there's also tons of plugins, profiles, dstyles, LUTs and whatever else you'd like

I basically don't edit photos anymore now that I'm with Fuji. It's not like I'm artistically opposed, the extra step was basically ruining photography for me, I simply don't have the time.

I still shoot jpeg + raw though because I may be lazy but I'm not insane :p

I got an RNI pack and have been very pleased. Especially the slide simulations. https://reallyniceimages.com/

I use the velvia function + artificial grain in Lighttable, though I am very amateur.
