Woodworking projects are the hardest of these. I've installed my own under the sink RO and it's relatively self contained 2 hour work whenever I move. Yet there are unforseen like tighter spaces, old plumbing that needs replacement of valves etc. But woodworking is a different and more rewarding beast. I usually spend 6-8 hours and spread that over a week, doodling in my notebook with rough drawings and cutouts before I touch a tool for any project. A few very important/clever thing I also learnt from woodworking experience was never finishing the whole thing at once if you can break it into pieces. Get 2-3 estimates from professionals to see how much they charge vs your time estimates. Make smaller projects that you can use to transfer experience to larger ones: working with wood fixtures on drywalls or built into sections of them are great practical examples of this.
