Starting with soldering, I find these 200$+ recommendations (regardless of which tool) hard to justify.
# Soldering iron
I'd recommend the Pinecil V2 with IronOS. https://github.com/Ralim/IronOS
# Solder fume extraction
I've built a simple fume extraction with an old plastic case, a 120mm fan and a sheet of carbon filter attached to a 120mm dryer / air conditioning hose. Around 15$ and good enough for soldering from time to time.
# "Microscope"
I simply use a strong (10x) magnifier glass with a LED ring (around 15$ on Amazon). I can't tell you how often I also used this thing for other purposes.
# Desoldering Pump
Because I needed it (beginners won't) I bought a ZD-8965 for 100 bucks and I'm very happy with this thing.
I have whole list of cheap beginner to intermediate equipment, that'll do until you solder (semi) professionally.
With you overall, but given the toxicity of the fumes some quality / rated fume extraction might be the one area where cheap/self made item isn't worth it
I've had bad experiences with USB irons, they generally don't have stellar compatibilty with USB power banks, and when your 60W iron can only draw 20W from your 100W power bank or PSU (but sometimes it works).
They even come with these compatibility wikis of what PSU or bank to buy.

How well does the pump work? A couple times I've had to desolder a connector or IC with lots of pins from a PCB and it's a painful process. I've always wanted to buy one of those, but I've seen lots of reports about getting clogged easily.
I rarely desolder, but I can easily justify a hundred bucks if I can avoid all that hours of work, where I'm also risking damaging an IC, lifting a pad, or something else...
