Lazard levelized cost of energy analysis a nice place to look at summaries overall of the cost of different energy sources.

For off-shore wind, you can also take a look at recent UK off-shore wind contracts, which are coming in at <40/MWh GBP (37.5GBP which is $42 USD). That's the guaranteed price the wind producers are contracted to sell their electricity at, so the actual pre-profit cost is absolutely lower than that.

Can also see back here discussion of on-shore wind purchase agreements in the US for $20 / MWh in 2019, which was noted as being more expensive than just the natural gas fuel itself per MWh (before this whole Russian gas crisis skyrocketed the prices), without considering actually amortizing the cost of building the gas power plants.

I'll admit though, my 'north of $100 / MWh' number for gas is a bit fluffy. It's true if you look at peaker plants in general (which are expensive because of such low capacity factor meaning ammortized capital costs / MWh generated are high), or if you look at current natural gas prices for gas generation in general, but for pre-crisis CCGT baseload, costs were definitely still well under $100 / MWh.
