Yes, ZFS is commonly known for heavy disk I/O and also huge RAM usage, the rule used to be "1GB of RAM for every TB of disk" but that's not compulsory.
Meanwhile, about BTRFS, keep in mind that Synology uses a mixed recipe because the RAID code of BTRFS is still green and it's not considered production ready. Here's an interesting read about how Synology filled the gaps: https://daltondur.st/syno_btrfs_1/
The only place ZFS seems to use a sizable amount of RAM is for the arc memory cache system which is an really nice feature when you have piles of small file access going on. For me some of the most high access things are the image stores for lemmy and mastodon that combine up to just under 200GB right now but are some crazy high number of files. Letting the system eat up idle ram to not have to pull all those from disk constantly is awesome.
