I’m in a fairly same position. I have an ash strat body I didn’t grain fill enough. After spraying nitro the grain texture is still there (originally I wanted it smooth) I’m not sure how to get the orange peel out as I’m scared of dust from sanding and/or cutting compound getting into the grain and not being able to get rid of it. I did spray one flash coat to see if I can get away without sanding but it didn’t have much affect

Grain filling by building up enough clear coat is difficult for two reasons. One, it takes a boot-load of clear to level out and getting a top coat that thick to cure will take two lifetimes (probably literally).

If you do sand the existing nitro, you should be able to clean it adequately with air (if you have a compressor) and thoroughly wiping down with naptha (shellite) or just naptha if air is not an option. I wouldn't recommend using cutting compound unless you know definitely it has no silicone or oil products in it.
Either of those will be problematic with adhesion of subsequent coats.
