Because with the biomedical equipment we are testing - we prefer to
have the minimal loss possible. And another reason I'm looking into
this because we have some RG58, RG58AU, RG174, RG59 (75Ohm, which we
don't need/can't use, but people still try to use), so I would like to
keep everything to one type only, if possible, to avoid confusion. And
since I'm getting this one type only, I would like to have the best one
possible.

That's the idea I was coming to after reading on the subject... But,
would I be able to use RG213 for both RF and data? Most of my signals
are data. RF signal I currently have is 10Vp-p (0 to 80MHz), it could
be greater voltage/frequency in the future.

Thanks,
Vitaliy
