There's no obvious good (nor bad). One important factor is what kind of node you'd like to run, and all of the following is about running a routing node. If you send/receive a lot (for whatever reason), things are very different.

I wrote down some ideas on https://c-otto.de. If you decide to open a channel to my node (c-otto.de), it needs to be 10M sats or more. Furthermore, I regularly close channels if they don't perform (in comparison to the other channels). For this I take into account how many sats are "stuck", see https://github.com/C-Otto/lnd-manageJ/blob/main/rating.md for a more detailed explanation.

In general I'd recommend opening (and maintaining!) just a few larger channels, instead of having a higher number of smaller channels. This, of course, depends on how many sats you'd want to have on your node (which, then, is a hot wallet). If that amount is below 5 BTC, I'd recommend not running a routing node.

I personally really liked Alex Bosworth's talk (from five years ago): https://www.youtube.com/watch?v=HlPIB6jt6ww

If you're inexperienced, I suggest you start slow. Just a few channels, not a whole lot of liquidity, to get your feet wet. You'll learn a lot (and you have to learn a lot), and you'll need some time to adjust your tooling.
