Get stuff that is easily replaced.
There's a lot of truth in this.
I went the DIY route. The first set of LEDs I installed where the stick-on strip light. I mounted them in aluminum C channel on the front of the facia. They looked great and had an interesting effect. The problem is, when one of the LEDs dies, everything after it goes out. This started happening after about year 3. It required climbing on a ladder once or twice a year with a soldering iron to cut out the bad LED and solder/glue in a new one.
This last year I pulled down all the existing lights and replaced them with wired LEDs every few inches in custom J-channel mounts that got screwed to the backside of the facia. If a LED goes out, I can pull down that entire section and replace the one LED in the comfort of my shop before putting it back up.
The Govee lights are nice. The app isn't horrible. The spotlights in the front of my house are Govee, but I replaced their controller with a DIY one that is the same as the one I'm using on my eaves.
We recently had a conversation in our neighborhood. Half the people went the DIY/Govee route, the other half had Jellyfish lighting installed. Driving around, you can't tell the difference.
I'm not sure what I'd do if I had open soffits like the OP. Clipping and reconnecting every single LED on each side of the soffit would be horrible and I agree that the metal track running across the bottom of the soffits looks weird.
