I'd say that this is going to be one of the easiest surface mount (SMD) soldering jobs you'd ever do. Removing is easy, adding is hard. Fwiw, my first time doing SMD I was really nervous but then found it to be quite easy and so it opened up a lot of things for me (making and repairing). It is much easier than you think (often easier than through hole!), just when placing something you need to hold it in place (or use a heat gun, making these sometimes easier). Here's a short video if you want some guide[0]. As for soldering tips, any would be fine, but I learned that the flat tips, like this[1], tend to be my goto rather than the pencil like tips. The mass helps it keep heat and the larger surface area helps you transfer that heat.

Professionals use chisels ;) : [link] [1] [link]

Soldering surface mount devices doesn't seem to be too bad, actually. Here are a couple of short videos: [link] ▶ this video

Yes, drag soldering was the only technique I considered. However, it didn't work very good. As said before, the main problem was that solder created shorts between pins, and some others were left with bad connections. I also tried to use braid to remove the excess solder, etc., but I felt the more I tried to fix it, the worse the result. I once watched this video about SMT soldering, and while the guy seems to be using just a soldering iron and flux, the result is outstanding. I don't know however which specific equipment and solder/flux he is using, and if it's real or there's some kind of trick involved :-D ▶ this video
