No recommendations, only comments on electric bass strings in general:
One factor is string tension, which influences how the strings feel ("wet noodles", etc.) Switching between high-tension and low-tension typically requires truss rod adjustment. Some companies publish how many pounds of pressure their strings provide, some don't, some just hint ("slinky", "low-tension flexible flats", etc.)
Another factor is manufacture, but you probably already know about the general tone and feel differences between round-wound, flat-wound, tape-wound, etc. and their many sub-varieties (e.g. nickle-wound, hex-core, etc.).
Then, within each manufacture, even at similar tension, there is tonal variety. For example, I wanted to switch from a round-wound "zing" to a flat-wound "thump" but without changing my truss rod. I found that my rounds (GHS Boomers) were a high-tension string, and that both D'Addario Chromes and GHS Precision Flats were similar in tension. But Chromes are known to be one of the brighter flat-wounds, and Precision Flats are know to be among the darker-sounding. I tried both, found this to be true, and selected accordingly.
I'm an engineer type, so this kind of anal-retentive research is right up my wheel house. More normal people might just throw on the Cobalts and see how they like them. You be you. And have fun.

Agreed - strings in general are so very subjective - it's like ice cream, so many brands - so many flavors.
My Aerodyne was my first bass & I strung it
with Black Beauties just because it looked cool. Later I did some non-invasive mods as Inwas underwhelmed by the pickups, later on I found I was not playing it as much - I have become more of a 5 string player & considered selling.
I got involved with an music circle jam group & was their primary bassist for several years - we did allot of acoustic roots type music & some oldies & I was looking for more of a classic old school thump, a set of DR Legends & the Aerodyne became my go to bass for those sessions.
Later I discovered Ben & Jerry's Chocolate Therapy

But that, my friends, is a discussion for another
