It can be difficult to get a comprehensive picture of the range of lenses available for the RF mount, and even more so for the APS-c optimized lenses. The major manufacturers I'm aware of are Canon, Sigma, and Tamron, the latter two being fully licensed by Canon and therefore most feature-compatible with the RF mount. There are other manufacturers but I personally don't pay too much attention to them.
For your starter lens, it appears that you are looking really budget...not only the slow kit lens, but used at that. Given you interest in bokeh, I just came across the SIGMA 18-50mm F2.8 DC DN Contemporary Lens. It covers a little broader focal range but has a big advantage in max aperture. It costs more, but might obviate the need for a second prime lens for bokeh.
You intent for a prime lens is quite ambiguous so I'm going to infer that you are interested in a "normal" lens. What focal length do you use on your XT as a street or normal lens for shallow DOF compositions? I would think you aren't using 40-50mm lenses but rather lenses in the range of 28-35mm. As pointed out above, 35mm is about 56mm FOV equivalent. I personally really liked the EF 28mm f1.8 on my APS-c EOS M5.
I will second the recommendations for the RF 35mm f1.8 (used on my R7, a bulkier camera than the R50). It is a little long [focal length equiv] but that is a matter of taste and photographic goals.
But I also just came across the Sigma 30mm f/1.4 DC DN. This one is falls right into the "normal" range.
For myself when I was building an RF-s kit for my R7 last spring, I chose:
-- RF-s 18-150 as my walk around. I liked its predecessor on the M5 , my caveat[/] being that I do very little social situation and people photography so the lens length wasn't an issue.
-- Tamron 11-20 f2.8. I had determined for me, traveling required a minimum 16mm FF equiv in my kit. The R7 has enough resolution to shoot that wide and still retain data and have sufficient room for cropping. That may not be true for a 24MP APS-c sensor, but this use case doesn't seem applicable to your inquiry
-- I also have the RF 16 f2.8 as an early attempt to get better bokeh and a little wider FOV than the 18-150.

Hope these suggestions help.
