I have a fairly recent DS920+ and never had issues with containers - I have probably 10+ containers on it - grafana, victoriametrics/logs, jellyfin, immich with ML, my custom ubuntu toolboxes for net, media, ffmpeg builds, gluetun for vpn, homeassistant, wallabag,...
Edit: I just checked Grafana and cadvisor reports 23 containers.
Edit2: 4.4.302+ (2022) is my kernel version, there might be specific tools that require more recent kernels, of course, but I was so far lucky enough to not run into those.
While gluetun works great, there are other implementations of wireguard that fail without the kernel modules. I've also ran into issues from containers wanting the kernel modules for iptables-nft but Synology only has legacy iptables.
