user126793: I'd love to see charts with stats on percent of utxos by invoice address type (specially P2PKH, P2SH, P2SH-P2WPKH, P2WPKH, P2TR), over time; and same for percent of coin supply.
No doubt I can pay a company to access these numbers. Is there any alternative free as in free beer? I could pay my own time working my way through some open source software able to do this.

user5406: While I think Pieter's answer provides exactly what you were asking for with the UTXO set repartition by output type, I think that you may also be interested in the Output Types by Count chart on transactionfee.info:

The site has also more related charts that may be interesting in the context such as

Input Types by Count
Output Types by Value

and various charts for specific output types.

user208: You can find the first on https://txstats.com/dashboard/db/utxo-set-repartition-by-output-type?orgId=1. For a version weighed by value you can look at the graphs of the individual output types on the same site.
