I had a quick look through the EAA document.
The images are very impressive and show what EAA can achieve. It does not make sense to compare EAA with Astrophotography which uses far longer exposure times and a lot more post capture processing.
But it is clear from your posts that you aren’t interested in the technology driven approach. To observe Nebulae and Galaxies you really need very dark skies. Star Clusters and double stars, not so much, because you can increase the magnification to darken the background.
I would go with option 5 which will make it much easier to come to a purchase decision. Availability of equipment will likely return to normal when the pandemic is over.
