First, it might depend on how you want to learn Buddhism.
Even if you say Buddhism in one word, the characteristics of the sect change depending on which of the vast sutras is used as the main text. It can be broadly divided into [monastic Buddhism] and [lay Buddhism]. If you are prepared to become a monk and go through strict ascetic practices, I recommend the [monk Buddhism] sect. However, if you want to learn while maintaining your current lifestyle, for example, the “Jodo Shinshu,” which is [home Buddhism], might be the best recommendation over denominations for monks. If it's a temple of the Jodo Shinshu sect, I think they'll be happy to tell you that no matter where you jump into it, they are doing workshops and puja ceremonies.
However, there are also places such as Zen temples that actively host Zen meditation sessions for the general public, so I highly recommend those as well.
However, there are also sects that have a style where they curse other denominations against Kechon Kechon Kechon of Borocas, say that we are absolute, and completely paralyze making judgments based on your own thoughts, so I don't really recommend that one.
May you have a relationship with a good teacher. Worship
