Recorded video has 15fps. I have to manually add "-r 15" to avoid speeding up. Maybe there is should be some builded-in argument like {W} and {H} but for the framerate. VP8 dont have that problem.

Doesn't look like it's speeding up to me. Which player and codecs are you using?
I can't add the {F} parameter because I don't have it while inside the Editor.

I checked again. It looks like PotPlayer's (video player that I use) built-in ffmpeg decoder vp9_cuvid treats 15fps or 5 fps video as 25fps and speeds everything up.

Also DXVA decoder works fine in PotPlayer, but reports 25 FPS, and correct "actual fps", VLC Player just dont play video at all. Standard Windows Media Player and "Movide & TV" works normal. Also no "framerate" property in file properties -> details if it should be.

You can add manually the FPS to the params text box (as you are currently doing) and save it to always use that (as a preset).

Not sure what else to do in this case.
