Wagos my man, wagos. Its wire nuts from the future.
Kill the breaker undo whatever the monstrosity is. Each hot, neutral, and ground gets its own Wago. You buy the type that has enough holes for your problem. If theres 3 hot legs that all should all go together after you remove the fixtue get (3) 3-holes (one for 3 hots one for 3 neutrals one f0r 3 grounds). Strip the hot wires so theres no bare copper outside the Wago and clip em all in the Wago, do the neutrals and grounds in their own wagos and your done. No fire haze. Safer than wire nuts and easier. And I'm not a salesman just used em before.
probably you need 12awg size (the thickness of the copper cable)
Hardware store or amazon. Seriously easy. Cheap. No need for a box. Works just as well for weird 4 wire 277v or whatever.
.....just dont put hot and neutral together. Hots with hots neutrals with neutrals.....
Well if you want to really help pollinators putting in a little more care than zero will pay big dividends.
I'd say build or buy a planter, 4' ish or smaller, lug some good dirt up, and use an ollas in the center. An ollas is an unglazed terracotta pot that you bury in the centerof the planter with the spout sticking above the dirt. then fill with water once or twice a week or so and the water slowly leeches out and waters the planter.
Pick out any plant that flowers that you like thats labeled as a perrenial and full sun. Some will be labeled as pollinator friendly. But the bees in my area go nuts for anything, cucumber pepper I had a hummer go for bell pepper flowers once.
Get like 4-6 plants for a 4' planter, depending on how big they get. Plant em. Water em real good for two weeks to get the roots established. Like every day water em for two weeks. Then you can go to using just the ollas every so offen and some extra water in heat waves. After 4-6 months sprinkle in some fertilizer to help keep the nutrients in the soil good.
Over winter, take the ollas out to avoid a freeze. Put back in spring. Probably a 2L ollas or small is all you need.
If you really can't be bothered, try hardy hens and chicks. They are small plants that come in lots of variety and make small baby plants. You can pinch off a baby plant and stick it in a random rockwall and it will probably survive. They aren't gonna help a pollinator though, more ornamental. Or get into cactuses.
