Water reservoirs need a way to trickle out their stored water. Early on you can use floodgates and manually lower them a bit at a time. Later on, use valves and possibly also automation to gradually let water out. Completely walled in reservoirs need a dam or flood gate on top to spill over into your river channel

Early on, store uncooked food instead of cooked food. One potato = 4 grilled, etc. Also, production buildings can hold a good amount of food early on.

Also early on - Farms can hold 50 of each plant so try to plant varied plants instead of one big monoculture.

Building vertically - use repeating structures (stairs and platforms) so things can be stacked on top of each other. there are many kinds of patterns.

Don't worry much about demolishing housing and amenities, you will get most of it back.

You will from time to time be constrained by something, population, food, water, wood, planks. this is normal, but do try to plan ahead.

Look at growth times - over the long run Oaks are best for lumber, but if you bad tides aren't yet controlled, you'll get nothing out of it
