I have had 3 different sets of sofas/chairs in the last, perhaps, 7 years. Neutral colours means I can change the fittings to whatever I feel like. What I don't want to do is repaint everything to match.
Neutral colors aren't as appealing to me at some level but I'm also less likely to tire of them, and as you say, I think they're more compatible with other changes.
I've wrestled with this in some recent remodeling too, thinking a blue would be nice here, but decided against it because I didn't want to change my mind later. But I was remodeling, so maybe it's inevitable anyway.
I think so much is disposable in our lives that maybe we gravitate toward colors that seem less ephemeral.
But with things like mixing bowls, measuring cups, etc, having bright colors is incredibly helpful if someone is in the kitchen with you - "give me the red cup" is easier to understand than "give me the 1-1/4 cup, no that other one over there".
After a couple of months, I regreted it, and my next phone was naturally black.
Life is too short for fucking beige. Build a space that reflects what you love and if what you love changes, so be it, change your space then. But there's no reason to shortchange yourself now in subservience to a future self you may never become.
