What size battery does a 2017–2022 Honda CR-V take?

BCI group 51R, rated at 410 cold cranking amps from the factory. Group size is a physical dimension and terminal-position standard, so a battery from a different group may not clamp down or may put the terminals on the wrong side.

How many CCA does a 2017–2022 Honda CR-V need?

At least 410 CCA. Going higher is harmless and helps in cold climates; going lower is how a vehicle that started fine in October stops starting in January.

Does the 2017–2022 Honda CR-V need an AGM battery?

The factory battery is a conventional flooded type. AGM is a valid upgrade, but never downgrade from AGM to flooded.

Where is the battery on a 2017–2022 Honda CR-V?

Engine bay, driver side.

Does a 2017–2022 Honda CR-V need the battery registered after replacement?

Factory 51R is rated ~410 CCA; Honda's replacement is 500 CCA and that is what you should buy given this generation's parasitic-drain history. Some owners upsize to a Group 47 (H5) with minor tray modification. It fits with more reserve capacity, but a quality 500 CCA 51R is the drop-in fix.
