Been thru the same stage on my setup where the wall looked great at night but stuck out like a sore thumb with the lights off. The thing that helped most was painting the trim the same color as the wall instead of leaving it white. Sounds minor but the whole thing melts into the room once the shadow lines are gone. I also ran a bead of caulk along the edge where the frame met the drywall, sanded it back, and touched up the paint. Took an afternoon and made the frame look built in rather than bolted on. For the patch marks, don't rush those. Thin coats of filler, sand between, and prime the spots before painting or they'll flash back at you every time light hits the wall at an angle. Prime and paint the whole wall corner to corner if you can, touch ups always show on big flat surfaces. On the extra strip around the shelf, I'd say do it. I added one behind my shelf later and only wish I'd run the wire before closing everything up. Leave yourself a spare cable loop tucked behind somewhere, you'll thank yourself when you change your mind about placement six months from now. Also check what your power supply can spare before adding length, easy to forget the first run is alredy drawing plenty.

Following the same slow grind on my own wall right now, except mine is a floating desk instead of a shelf. The thing that slowed me down was the paint sheen. I used an eggshell on the wall and the reflection from the strips made every little trowel mark glow at night, so I ended up going back over it with flat and the difference was night and day. Worth checking before you do your final coats because sheen hides nothing once the lights are on low. On the extra strip, I say plan for the wiring now even if you install it later. I skipped that step and had to fish cable down inside the wall with a coat hanger and a lot of swearing. Also, my run dimmed noticeably toward the far end untill I fed power in from both sides, so if your shelf strip ends up being a few meters, think about where the feed lands before you stick anything down permanently. For the small finish jobs, I made myself a rule of one task per evening. Spackle one night, sand the next, then paint. It kept me from rushing the boring parts and burning out halfway through, which is exactly what happened on my first build and it sat half finished for months.
One thing I'd add on the shelf strip is think about the diffuser before you commit. I ran bare LED's behind mine at first and every individual dot showed up on the wall, so I swapped to a strip with a milky silicone sleeve and it went from pixel lights to a clean glow. Also dial the brightness down in WLED itself, I cap mine around 40% for the shelf because full power is blinding from the couch and it keeps the heat down on the wood.
I've found that once you get past the strips, the power supply unit and controller hiding is where the real grind is. Planning that enclosure space before you close up the wall is huge. You gotta know exactly where that hardware is gonna sit because it'll take way more effort to fish the PSU out later. I ended up using a small, custom-built box to keep the heat managed and totally invisible. Otherwise, your neat setup just turns into a tech graveyard near the wall!
