I was wondering which tonearms allow for easy adjustments of VTA, SRA, azimuth, and such on the fly, i.e. without having to go through a lot of effort to make changes, like unscrewing a tonearm from the mount in order to raise the tonearm, etc.

The best of them is Reed, very few tonearms will give you azimuth on the fly option, vta on the fly is there too, so look for Reed 3p for example! The engineering of this tonearm is amazing, the build quality too. You can find some images of Reed 3p "12 in my old system here.
Regarding vintage tonearms with such options:
The best one (imo) is Lustre GST-801, but without azimuth on the fly (except for headshell with azimuth adjustment), however the VTA on the fly is there. Nice tonearms for a reasonable price nowadays!
Technics EPA-100 (and EPA-100 mk2) is another great tonearm with VTA on the fly.
For Fidelity-Research (and new Ikeda) tonearms we have to buy VTA on the fly base separately and this B60 (or IT-VTA-06) base alone costs more than the entire Lustre tonearm with VTA on the fly. Ikeda headshells will give you overhang and azimuth adjustment options.
