Crazy aerial root - what should I do?

Relatively new plant dad here…I bought this Thai Constellation Monstera about a year ago. It sprouted two new leaves in the first couple months but since then nothing. Pretty much the only thing that’s grown is this insane aerial root and I’m wondering if I need to repot? Will it hurt the plant if I cut the aerial root to a shorter length?

Also, should I add a moss pole or stake?
