EF to RF Lens migration.

So I recently replaced my 800D with an R10, and have the following ef-s lens, ranked in order or most used. Use case is mostly landscape/club level motorsport/general holiday photos. Dont really do much in the way of portrait, wouldnt mind giving astro a try. I have the canon ef-rf adapter.

Canon EF-S 18-135mm f/3.5-5.6 IS STM (General purpose/motorsport)

Canon EF-S 10-18mm f/4.5-5.6 IS STM (Lanscape)

Canon EF 70-300mm f/4-5.6 IS II USM (Motorsport)

Canon RF 28mm f/2.8 STM

Canon EF 50Mm F/1.8 STM (Not used often)

Is there anything there that would be worthwhile replacing as an affordable upgrade with EF/RF glass in the near future ? Ive been looking at the Tamron 17-70mm f2.8 for general purpose lens with good low light, and the Sigma 10-18mm f/2.8 for low light landscape, though I mostly use the 10-18 with a tripod so not sure if its worthwhile. Im not in a rush to buy, but gives me ideas of things to look out for that might pop up on marketplace etc.

Budget would be say $1000usd (actually based in NZ but nobody know what our pesos are worth)
