What’s a good plan after NTR?

Beginner runner here that’s due to finish their 12 week NTR plan this weekend!

I’m really enjoying running and want to continue the habit, so as a beginner should I focus on distance or speed more on my next plan?

I’m a slow beginner runner that would want to do a 10k but would also want to get faster.

I know people say with distance comes speed but I’d like to gain more insight from more experienced runners.
