I make my x's with a backwards c and a c, like Computer Mondern and lots of fonts https://i.ibb.co/8LPsJKsj/image.png - doesn't look much like a chi or a times sign

No one in the target audience is using × for scalar multiplication.

My x looks like a cross in normal handwriting, but like two back-to-back c's in algebra. I developed this habit very young, and have kept it.

Not for scalar, but certainly for vector multiplication which a large part of the audience certainly needs a lot.
