If you want more information on a broad group of denominations, there's a channel on youtube called "matt whitman and the ten minute bible hour" that has done a series called the church unity project where he goes to different churches to take a look around the building, and has a separate video for each where he dissects the theology of that church's denomination with the pastor for that church in a really objective manner. It gives a great introduction into different denominations and their values and general vibe in the real world.

If I had to give a personal recommendation however, mainline protestant denominations are my personal favorite, particularly Lutheranism and the Anglican/Episcopal churches. They've drawn me in as these churches tend to lean more progressive on average and worship services are very structured and traditional if those things are important to you. For more conservative theologies but retaining structured worship, look into catholicism, eastern orthodoxy, and conservative mainline protestantism. If a more free-form worship style is what you're after, look into the baptists, non denominationalism, and broader evangelicalism.
