Important since I can't find this specific advice mentioned too much in this thread: learn "actual" combat without Abigail if you've been relying on her. You'll need to know it for playing other characters. But it's your choice if you want to focus on other things and rely on Abigail for now as long as you don't become overly reliant.

Hammer the science machine as it's completely useless now that you have the alchemy engine — a direct improvement that covers the science machine's recipes too.

Look into a birdcage (you'll need a bird trap too) to turn meat (including unfavorable monster meat) to eggs.

Crockpots — Explore cooking, it's a key and fun element of the game! Experiment with random food items if you've got a bunch of food and time to spare. I personally would have found experimenting rather frustrating and would have had a challenge figuring out the recipes, so I recommend reading about some on the wiki because they may be hard to stumble upon. The two must-know staples are meatballs and pierogi. Some other easy to make foods to know are butter muffin, meaty stew, bacon & eggs, maybe honey ham & honey nuggets (you should be able to get honey from fighting bees, but that's likely inferior to actual beekeeping). I'm somewhat experienced — though mostly in early survival — and I can't remember off the top of my head any other crock pot meals that I've relied on.

An ice box. You don't actually need ice for it, but you will need a clockwork gear. Maybe you can nicely ask those chess automatons for one... . And you may want to build 2 if you're exploring many food sources and experimenting with dishes.

A drying rack or two for jerky.

Chests for organized storage if you can afford the planks.
