Can i get answers about CARGO in Starpoint Gemini: warlords?

i just started playing Starpoint Gemini: Warlords. i have questions about "cargo". i am new to this game. should i sell all the cargo i collect? or can i use any of the cargo i collect for my own ship as in repairs? I cannot find any info on the proper use of collected cargo, like healing gel or utility bots. are these things i can use for myself and ship or is it all just stuff to sell? thank you!
