Could you play about with stuff stretched over wooden frames, and bass traps to figure it out before you do anything permanent? It's all quite subjective.

If your room is 'normal' size and construction you won't be able to fit large enough bass traps to be effective. You're right to have the concerns you have, it's a common outcome.
Best mitigation is speakers away from walls. Something dense behind the listening position, non reflective behind the speakers and convolution dsp.
There are some great books on acoustics, when you look at the acoustically perfect room you are ultimately trying to create, it's not a domestic room.
As an example, after years of measuring and moving things around the room I have has very little reflections, this is noticeable if you clap your hands in it. It also has controlled bass at the listening position but the rear corners have an extra 6db (that's double) at 50hz.
Bass flows like water across the walls and builds up in corners. It also reflects and doubles at certain frequencies depending on room size. All of this is predictable and software like REW can calculate frequency response from dimensions, including speaker position to help you.
Another basic improvement I believe in is tilting speakers about 5 degrees to the listening position. I personally find it helps with reflections.

I’m adding rockwool and a microperforated stretch ceiling to our living room to reduce reverb and general reflections. The ceiling is fucked and needs replaced anyway so it’s two birds with one stone.
Anyone know anything about room treatment? My concern is that I’ll absorb lots of high and mid frequency and little bass, resulting in a boring boomy room. Bass traps in the corners too?
