Tubes or SS?
I encourage selecting efficient speakers to keep the power need low, which makes it easier to try/afford tubes, and lower power tubes don’t make too much heat in a small space.
My small office system, I chose AR-2ax Speakers, avg 90 db sensitivity. 3 way, 10" woofers, individual volume controls of mid and tweeter. They sound terrific! Designed to fit ON or IN a bookcase.

I am using 10 wpc, in a bit larger space, 25-45 wpc would be plenty, and not too much heat.
If a mid-sized space, they can be stand mounted, or KLH or JBL Compact 3 way stand mounted.
