Reconsideration request approved!!! it was time!!! and now?

Very very happy, my site that has more than 10 years of life had been penalized about 4 years ago
That did not stop me, I kept working hard to keep up with the business
Now I have several unknowns

first, I have a mirror site that only changes the .com by .xyz
this site ranks well, now what should I do?
I should tell google that now I do not need this domain anymore
spend good money on the site, something like 2000 dollars, between links and seo packs, youtube video, hand written articles

This is the biggest unknown I have now, the rest I think I can solve it, everything would be to rank my site slowly

the most important thing for me was to go back to the name of my company first
now I have first #1 the name of the site .xyz and second or third appears my domain despenalized

This is not minor, since with the penalty my site appeared in all search results in the position #50 +

I hope you can guide me what steps I should follow, I am satisfied with having 20% of the visits that came before by google, since from other search engines and other sources I did not lose ranking
