I'm nowhere even remotely comparable to a proper furniture maker, but I can tell you some pitfalls to avoid.
Don't cut wood without eyes, ears, and face protection. The dust, noise, or fumes will get you one day or another, if without protection. I prefer earmuffs over earplugs, but if earplugs then use the ones which tether both ends together. For a face mask, I like low-profile half-masks like this one: https://www.kleintools.com/catalog/respirators/p100-half-mask-respirator-sm
Resist the urge to dive into woodworking by starting with reclaimed wood. For example, pallets are a cheap/free source of material, but it's a hodge-podge of different varieties, all riddled with nail holes, dents, and brown stains from rusty fasteners.
That's not to say it can't be done, but it certainly aggravates the process if you're just starting. I once came across a section of 2x4 recovered from a pallet, thinking that it would cut just like the pine I was used to. Instead, it wrecked two drill bits and burned a circular saw blade as well as itself. I later mailed a sample of it to the USDA Wood Identification Public Service, who informed me that it was Acer (Hard Maple). Up until then, I didn't even know that maple came in both varieties.
It seems hard maple is tougher than nails drill bits. I'm still learning.
White maple is my go-to for projects I want to keep. I love how clean it is and the large curvy grain patterns. Titanium bits and saw blades help and getting your saw blade sharpened after a couple of large projects is a good idea but you're going to be burning through it a lot of the time even with high quality brand new cutting tools. I leave an 8th extra on and bring it down with a belt sander to deal with the burn marks. Downsize drill bits by one size and use a file for holes that you will be able to see into.
If you use reclaimed wood don't assume all of the metal has been removed. Sometimes nails and screws break instead of working out and that can be easy to miss especially for someone checking a large amount of wood. If a saw blade hits a nail you potentially have a very dangerous projectile. Run a magnet over the wood while you're marking your cuts to make sure. If you're going to be working with reclaimed wood a lot a wand style metal detector is a good investment.
The funny thing is that a few months ago, I bought a wand metal detector at a ham radio swap meet for $20, as a gag. Now you're telling me that it was actually a prudent investment toward my woodworking projects??
This might be true, although I do it mostly so I can remove the earplugs and rest them around my neck if someone needs to talk to me.
The best PPE are the ones which have the fewest barriers toward using. Even the minor annoyance of having to set down untethered earplugs is best avoided, if it acts as a subconscious disincentive towards using PPE. Good safety policy adapts and accommodates this aspect of human behavior.
In a home workshop, there is no OSHA, so I'm fully responsible for my own safety protocols.
