Which lens should I pick up after the nifty fifty?

I have a Canon R8, not opposed to EF lenses though. I'm enjoying shooting with the 50mm but want to expand my horizons a bit. Been thinking about grabbing an 85mm...would you go with the RF 85 f2 or the EF 85 f1.8?

Is an 85mm forcing me into doing strictly portraiture?

There's also a Samyang 14mm f2.8 for a reasonable price near me. Is manual focus that much of a hassle to shoot with?

Idk, what are your thoughts /p/?
