OS LTS support barely matters when planned obsolescence is baked in at the hardware level. Wearing parts (eg. SSD) are soldered on newer macs and there's intensive efforts to make sure even if you have the tools you can't repair it.

Parts aren't available but if you get your hands on there's cryptographic parts pairing so it more or less can't be replaced: https://rossmanngroup.com/services/ssd-data-recovery/macbook...

Overall, i wouldn't count on "many good years left".
