Better to find someone who has similar interests and especially similar goals in life.
I’m planning on just finding someone who is more afraid of dying alone than I am :D
I read an anecdote about a dating service that made a very serious effort to do just that. They met once, parted friends, and never dated again. Afterwards the gal said it was like meeting a long-lost brother!
There’s something a bit different between a marriage dynamic and a friends dynamic, but of course only IMHO as a crufty old bachelor....

Not interests — VALUES. My wife and I have widely divergent interests. But our values (frugality and hating debt at the top of the list) mesh perfectly. These also include fidelity (there are many whose values include “open relationships”), honesty, marriage before sex, putting children first, humans protecting animals who can’t protect themselves (except good eating ones which we only ask they be put down painlessly), and other of the like.
Her politics cut more independent, mine conservative. She hates Trump, I can’t wait for his next public appearance and might actually vote for him.
I point out the latter to note that we share VALUES but not necessarily OPINIONS.
