For those who still remember Graphite, the team over at Grafana labs have started maintaining Graphite-web and Carbon since 2017 and it is still in active development getting improvements and feature updates. It might not scale as well as any of the other solutions, but for medium size or homelab setups it's still a nice solution if you don't like PromQL or InfluxQL.
for simple and fast monitoring solutions, i always opted for collected + graphite + grafana. In a containerized environment, it's so easy to deploy (0 configuration by default) and monitor a set of 50-100 nodes. Beyond that, disk tuning and downsampling (pre-aggregation) rules become important.
