So you say a bunch of soldering crap.... Do you have an external power supply for the LED strip? You won't be able to power a whole strip through the esp.
A tip on soldering - I had very little soldering experience so I bought an intensive set of double sided prototyping boards to practice on. With the help of some YouTube videos I was able to be comfortable cutting the stip and soldering leads to it without wrecking my strip or controller.

Cool! I use Weller soldering stations, but I also have a little USB-C powered TS101 that I love, it heats up fast and does great work and it's portable. I'd suggest checking that out. Get some 63/37 rosin core solder for its low melting point (and rosin core means it has flux inside of it). As far as connectors for your sensors, you could get something like this kit (which actually comes with 3 meters of 3 conductor 22AWG wire, which could do the trick).
Personally, I've mounted my ESP8266 boards to PCB boards and used right-angle pin headers (like what's on your sensor) to break out specific pins for power and sensors to keep things clean. In your case, you could use the kit above and just plug it straight into the board... I really like the M5Stack Core because they have a display and break out the pins nicely for you to access, but it's probably overkill for your project.
Good luck with the build!
The box I got for free. I’ll put a pic of the box it came in for you tonight when I get home. Easy enough to find one on Amazon I’m sure.
That’s the wiring on the back side of the pcb I made for the esp32, level shifter and buck converter

Are you sure the entire thing isn't DIY, not just the case? That display looks like a common standalone panel-mount voltmeter you can get off Amazon, and the board appears to be one of the standard prototype board sizes.
