Why couldnt we finalize it? What does this mean?

IIUC, it would fail to be finalized if it includes inputs that cannot be satisfied at the current time, e.g., due to being timelocked. Replaced this with a more generic FundingTxCreationFailed error.

But shouldn't that be handled by not selecting those inputs? Presumably the error should just be "we don't have enough (available) funds (right now)", no?

Well, IIUC they go through all previously unsigned inputs, try to derive the right wallet descriptor, and sign them. So in our case you're probably right, but while the word 'finalize' appears quite a lot it's kinda poorly documented what it actually does/why it's an extra step. I'll try to clarify with the BDK folks and will probably open an issue..

So, it seems that while individual inputs are signed before, the witness is just created and added in the finalization step. I'm still not quite sure when this step would ever fail in our case, since not having enough funds should already become apparent during input selection, i.e., during tx_builder.finish(). So, I'll probably just capture all that via the FundingTxCreationFailed error.
