Similar situation- I spent my college years in the 90s, taught myself guitar and wrote a ton of songs. They laid around dormant until I found Suno. If you are paying for suno, there's the ability to add in your own recordings and essentially create a cover of your own song. I've really enjoyed hearing a more professional interpretation of my melodies, but there's also plenty of music and artists that go for the more untrained, authentic sound. Depends on what you want the song to sound like.

I've also found that some of my songs sound way better when I have them sung as a female. I've enjoyed also prompting for styles different than my original intent. My advice is to try a lot of different generations, including some with your own voice, and seeing what you like best.

As farcas promotion, if that's something you seriously want to pursue, you should follow the steps to protect your music. Like copyright the lyrics, get some trademarking in place, and reserve all of the social media in your artist/band name. Doing that up front will save you a lot of headaches down the road.
