I feel like this poem isn't really about soldering, but if anyone is actually bothered by it, there are some options.
Unleaded solder and a decent fume extractor make the process cleaner. A decent soldering iron and solder wire with good-quality flux (e.g. Kester) makes it faster.
If you'd rather not deal with the iron, you can manually apply solder paste and use a hot air rework tool or even a heat gun (careful!) to melt it. (A proper reflow oven is better, of course, but that's pricey.) This makes working with surface-mount components much easier.
If you'd rather not deal with it at all, have a PCB assembled somewhere else. JLC is pretty cheap, especially on simpler boards.
Yes, you are quite correct in the first point. I've also met people who recommend crimping where possible as a safer and cleaner solution.

You can do a lot worse than a $55 temperature controlled hot plate. Plus you can watch the magic happen. Of course that only works for single sided boards. I've been very impressed with the results.
