Combining these queries? (Same taxonomy term same category as post)

Hi. I′m not to good at coding so I could use some help with this!
I have a single page which below the post shows more posts from the same category. Then I have another single page which in a similare fashion shows more posts from the same taxonomy term as the current post.

I would like to combine this to show posts from the same category and taxonomy term as the current post.

Code for “same taxonomy term”: https://pastebin.com/ebpbzfNi
Code for “same category” : https://pastebin.com/kB0n49Bd

If someone would help me with this I would be very grateful!
