Getting the correct OWrt image version

Yes, should be fine. In some rare cases the build system has built firmwares for devices in preparation for a new stable release which compiles fine but then causes issue when running (such as the switch on Netgear R8000 and Linksys EA9200 not working, see OpenWrt 23.05.0 - First stable release), but as long as you check known issues (see post above) it should be fine; I've personally never seen issues like this between minor stable versions.

Your device also implements a dual partition layout, so even if the flash goes bad in some way you can swap to a known working firmware on the other partition, so it's basically unbrickable, which is a nice bonus.
