Good morning Aymeric,
Different versions may consider different output scripts standard.
Your rule of thumb, post-SegWit, should be:
* If not P2PKH or P2WPKH, then wrap it in a P2SH or P2WSH.
There are more standard outputs accepted, but you can be reasonably sure th=
at P2PKH, P2WPKH, P2SH, and P2WSH are the only standard output scripts that=
are likely to remain supported in the mid-future (5->10 years from 2019).
Lightning uses P2WSH for its scripts.
Any m-of-n signing scheme in Bitcoin is P2SH (usually) or P2WSH (if you are=
cool).
Regards,
ZmnSCPxj
