If you can take a picture showing the overall layout (including the outlets) that could be helpful.
As for possible ideas, what about some thin LED strip lighting with power leading down from there to a Zigbee (or your preferred method) controller? The controller could then be handled by a timer, motion sensor, presence sensor, or however you want. You could choose an LED strip in a particular white, but you could also go with one that is RGBW or RGB+CCT if you want to allow for accent lighting.
The most "advanced" would be to use individually addressable LEDs (or addressable sections) so you could control each shelf (or even portions of shelves if you are highlighting specific items on them). A WLED controller could easily handle such a scenario.
My preference is to have single control of all lights.
Power to each light down through each section w/ having a ton of bundled wire in each section is a concern, I could cut/splice in each section to keep wire to a min.
I have no preference for a controller, have used a zoo smart relay in the past for some outside lights.
Do you want single color, RGB, RGBW/RGB+CCT, or individually controllable?
The first is easiest (just splice into the power lines). The second and third are similar (it will be more splices. The last would require more effort, planning, and certainly cost. All of them have different recommendations also...
A single controller might be nice, but then you have to run wires across the center line (and it might be getting too long from the looks of it). Likely easier to go with two controllers that you just mirror.
I have had good luck with the GLEDOPTO series of products. Below are some Amazon links for models that might be of interest. The first two are ZigBee, the third is a WiFi WLED (NOT Matter, but there are Hubitat integrations people have made for it), the fourth one is a Matter model (I have not tried one of their Matter ones yet). I added a fifth (that I found while writing this up) that is also an ESP32 WLED model but it includes and Ethernet jack(!).
Also a couple links for LED strips although I do not have a specific brand I rely on for those... I have used many different ones for different projects over time. I did not have any good recommendations for connectors or power supplies because that can vary by the type of LED strip you get.
Finally, I included one kit that I found while searching otherwise that was something I had not seen before. It is apparently an RGB (addressable) with separate CW and WW channels, making it effectively RGB+CCT. I ordered one of these because it seems so strange I wanted to check it out...
