It happens every few touches. Started with the upgrade to Sequoia. I'll touch the trackpad to start working in a window, and that window will suddenly expand to almost full screen. I tried resetting the default size (Ctrl F5), but that does "hold" next session.

Sounds like the new tiling feature. Try turning it off:
System Settings -> Desktop & Dock -> Tile by dragging windws to screen edges OFF
You can still do it while holding the Alt Option key and dragging windows. They will snap full screen, left, right, and top, bottom.
Thank you James. This worked for me.
Is the point of this feature to allow for tiling multiple windows and filling the voids so there's no desktop space peeking through? I'm trying to understand why this is even a feature.
I think there are two settings to switch off
My windows keep expanding to near-full screen upon first touching the trackpad.
