I've always had a soft spot for influxdb after using it for a self hosted datadog/newrelic etc solution many (6+) years ago with great success. Still use it in conjunction with telegraf and grafana for personal project monitoring, but I've not brought myself to upgrade from the 1.x series.
Hopefully it's improved, but last time I tried upgrading I found the UX in grafana to be subpar on the newer versions, as I recall you lost the autocomplete/UI to build your queries. Obviously grafana is it's own project but feels like they (influx) should invest more resource in areas like this to encourage people to upgrade - if you're going to do major upgrades make sure they have feature parity
Like you, I've stuck with Influx v1, Telegraf and Grafana. My policy is to upgrade only when there are significant reasons to. When I evaluated InfluxDB 2, there were no major reasons for me to switch. Of course, the data ingested in my case is relatively small. YMMV.
I looked at TimescaleDB but at the time there was no easy way to get data from Telegraf to TimescaleDB. Telegraf finally merged code that allows writes to Postgres databases, but it took like 3 years to do that.
Ultimately, I still stuck with InfluxDB v1 because sending data to it via the InfluxDB line protocol is so simple. I have a couple of bash scripts that use awk to transform command output to Influx line protocol and send it to InfluxDB. It's just so simple. I love it.
I love learning about new things, but the InfluxDB v1 keeps working fine so I may not switch from it until something forces me to do it.
Was very similar for me. No good reason to go V2, the new query language, on top of sucking for anyone that only uses it once every few weeks, also wasn't really supported well in Grafana.
I ended up trying VictoriaMetrics by near accident as infuxdb didn't like something on my raspberry pi, and honestly it has been pretty painless. It is Prometheus-like stack which means you can use any PromQL-compatible things with it. There is "all in one binary", and version split by functions.
VM have tools to migrate from InfluxDB v1. I ended up just sticking old influxdb data in one database, as I wanted to change the format of what I write to it along with the migration.

It also have agent that's job is to convert from various protocols, and do the scraping, that includes influxdb, and few other popular protocols.
have you given QuestDB a try? it includes its implementation of the InfluxDB Line Protocol, adds SQL for queries and can sustain a higher ingestion rate, without high cardinality limitations
