Powering and controlling LED strips, possibly switched from 120v lights? (alien.top)

I'm just starting my home automation journey, and could use some help figuring this out please.

I've got a closet with a regular dumb light switch that controls two overhead can lights (all 120v, no smartness involved).

I've just got some LED strips that I want to mount underneath the shelves, as accent lighting. The strips are 24v and came with no controllers. They are dimmable and color temperature adjustable.

Is it possible to set this all up in either of the following ways, while ensuring it's safe/code compliant?

turn accent lights on to the pre-set brightness and color temp levels when the main light switch is turned on.
turn accent lights on to the pre-set brightness and color temp levels from a second wall switch, that does not require batteries.

The part that's stumping me is finding a controller that will retain the brightness/color temp levels when powered off, and finding one that can accept a regular switch period.

For the high voltage side, any wire should match your breaker rating, so 14 gauge for 15A or 12 gauge for 20A circuits. The low voltage side shouldn't matter much, I've used anything from cat5 24 gauge up to 18 gauge depending on distance of the run.
