Keeping EF lenses, or worth it to update to RF

I have switched to mostly a RF kit after two years with my R5. I did not have a lot of L quality EF lenses when I bought my R5. I actually bought several EF lenses after I bought my R5 due to good used deals and high cost of RF L lenses. Over the last two years I have slowly sold off some of these EF lenses and now have three main RF lenses I travel with 100% of the time in my backpack. The RF 100-500, 15-35 f/2.8 and the 24-105 f/4. I have a separate Peak Design duffel that I take when I want my full kit with the RF 800 f/11 and RF 100-400. In the PK bag I have my Sigma 14mm f/1.8 Art, EF 24-70 f.2.8 and EF 85 f/1.8. I also have a EF 70-200 f/2.8 II, but I don't travel with the lens unless I am doing indoor sports. I also have several other EF lenses that are mostly used by my kids.

If I was going to replace any of my existing EF lenses with something existing on the market it would be the 70-200 f/2.8. I did not buy the RF lens because my last daughter doing sports has decided this year to focus on academics as she started HS. I have not used my 70-200 in almost a year. I really like the size and weight of the RF 70-200 f/2.8 and if I have a need again for fast indoor action I would sell the EF and buy the RF.

My biggest pain when using EF lenses at first was remembering the adaptor. I also hated changing it in the field. I finally bought several adapters to keep on my main lenses. Took awhile to get the adapters, two years ago they were in short supply.

I like my current lens lineup and really don't have a burning need for any additional lenses. Maybe if Canon came out with a smaller and lighter UWA lens like the Sony 14 f/1.8 I might be tempted. Would be nice to have something smaller for Astrophotography.

I think your current plan is good. If you want to try RF lenses you could always rent one to see the differences. Don't rush out and change your kit until you know what you want in RF lenses. Adapted EF lenses work great.
