Churches are very different and even different services at the same church can be very different.
So do 'shop' around for a while.
It is really important to find a church as the church is the body of Christ. Christians are Christ's body. You cannot be a Christian on your own.
A church should also support you in developing your spiritual life, learning about your faith and living it out.
As you grow in your faith, your understanding may change, and you may find that this church isn't right for you any more. That often happens.
If you are into bible and talks at the moment, then maybe an independent evangelical church or a baptist church might be helpful. (Though they will probably have a strong community element and will talk to you - not everyone likes that of course)
I'm Catholic, our services are very formal, with lots of scripture, but the 'sermon' will not be long or complicated. Communion, (the actual, literal, body blood soul and divinity of Christ) is a big focus. We see our worship as something we do for God.
So although my easiest prayer method is using praise and worship music, I'm happy with chant and hymns and speaking when I go to Mass, because Mass isn't for me. It's for God.
The church of England varies greatly between those that are almost like the independent evangelical or Pentecostal churches and the Roman Catholics, so you need to treat each CofE church as an individual church, when visiting.
