You will love it. I actually use a mouse with the trackpad. My left hand uses the trackpad and the right uses the mouse. It can be done. It is an alternating rhythm that I have gotten use to. Since I attach my M1 Max MBP to two 27" 4K monitors, I have several heavy apps running at the same time - Photoshop, Premier Pro, sometimes Audition plus email and a web browser. I actually like the trackpad for delicate detailed movements and the mouse for the broad strokes.
You will find your new MBP is amazing and fast - enjoy!
