I took linear algebra through a community college and had one of those rare, really awesome CC instructors. He had spent most of his career at Cray and later Raytheon and then semi-retired as a community college instructor. He took time to make really great interactive Jupyter notebooks. That combined with 3 brown 1 blue videos really made linear algebra click for me.

My only regret is that I took the class as a six week short course. I think my recall would be better if I had taken the full semester. We covered all the material, but missed out on the longer spaced repetition. Linear Algebra was by far my favorite pure math course, I hope to revisit it soon. Maybe Strang's lectures are the way to do that.
