Yeah, porting the project to Reaper took a while, since Reaper does not support the DAWProject format and the converter to turn the dawproject file from Cubase to a reaperproject did not really work that well, so just imported the midi and set up all the tracks/insruments manually 😂. The sound is probably not 1 to 1 to my initial Cubase version since I had to swap out the Cubase stock plugins for reaper ones.
I've found some helpful tools and guides that have helped get the Reaper midi editing feel a bit better, but Cubase is still the king with how smooth the workflow is natively in it.
The first tool that I found and has helped me, is the multi tool script from Julian Sader. This script adds most of the same midi value manipulation that Cubase has out of the box + it also works in the arrangement view, so you can use it there for automation

The other good resource has been Seventh Sam's blog guides on setting up the MIDI Editor, I found from there how to make a button for toggling multi track editing on/off in the MIDI Editor, which has also saved me a lot of head ache, also found out about the Multi Tool script for those. Seems like he has some new guides on a script to set up CC lane preset buttons to the bottom of the MIDI editor which I think I'll have to try to set up.

Binding the action to change the grid sizes is also handy, I did that in cubase too (1/4, 1/6), but there is a user made script tool to dynamically change the grid size based on zoom level thats great too.

Probably the one thing that helped me the most on this one, specifically in regards to working with orchestral/sample sounds, was the new Articulation System by Jesper Ankarfeldt, since before the jam I had set up expression maps with negative track delays per articulation for all my sounds in Cubase, as that was finally a function in the newer updates, and this reaper script also makes it possible to have per articulation delay values as well,
I still had to remake all my Cubase expression maps again in this Reaper script, but luckily this one has a easy to use GUI editor compared to the older Reaticulate script where you had to edit a config file and assign the keyswitch note values with their actual midi numbers 😩 (so not C#3, but 86 or whatever the corresponding number for it is...).

One script that's not really just for MIDI but I like a lot is nvk_SEARCH, which adds a handy search window that you can use to pretty much quickly search anything in your project, be it actions, track, trackpresets etc. They make some other sound design focused scripts too that are iirc heavily used and recommended by game audio people, but I haven't done much sound design so cant say much about those.

This is not MIDI related too, but a handy script to get the track disabling/enabling functionality that Cubase has that I use on my orchestral template to turn off tracks not in use

And pairing that with custom scripts that hide and show those disabled tracks, helps keep the project not looking too cluttered. I have bound the hide and show scripts to shift + Q and shift + W respectively myself.

Those have helped me a bit to make the editing feel smoother, but I've only used Cubase for years before Reaper so it's probably going to just take time to get as comfortable with Reaper as I had gotten in Cubase over the years. The only real annoyance I still have with Reaper is that the whole program gets really laggy graphically in bigger size projects, like in my project file for this jam the GUI feels really low frame rate when scrolling around in the MIDI Editor and Arrangement view.
If I could somehow get the lag fixed I'd be pretty happy with my Reaper setup, but from what I've read on the forums there is no solution to fixing the laggyness unfortunately...
But anyway, that's all the scripts/tweaks I've found to help, still not as fluid feeling workflow as I had in Cubase, but probably just need to keep using Reaper more to get comfortable with it (hopefully🤞).
