My personal preference is 12v ws2811 bullet-style voltage-regulated nodes. They’re extendable, individual nodes on a strand are replaceable if you’re willing to do some cutting and crimping.
I like the 12v because you can go for longer strands without losing colors from voltage drop. Regulated over a resistive voltage divider = less heat.
As has been mentioned, you can install WLED onto a microcontroller and have a web-page for a remote control.
