electric oven to cure at a lower temp.I am new to understanding control systems?

Good morning,

I’m wanting to build an electric oven to cure at a lower temp. (165 deg.F) However, I am new to understanding control systems

Constraints:
-estimated need of 2500-3000 Watts to warm parts inside of 80 cubic ft
-must include a fan to circulate air inside
-oven needs to regulate temp. at least within 5-10 deg. accuracy

Questions:
-what kind of power do I need? 240V? 3 phase?
-can you list all the parts I need for this oven to work? *I need it to regulate temp and turn on a fan. A touch screen would be nice for me to turn on the oven and adjust the temp if possible.
-do I need fuses after every component?
-what kind of wires do I need?
-do I need 24VDC or 12VDC or none at all?

Suggestions are appreciated.
