> The coverage on the BandYou card seemed comparable to the Orange SIM, more or less,

officially less. that is a fact. in France BoT network is well-known to give priority to urban areas.

> 4G coverage was sporadic and somewhat unpredictable.

only 600 antennas / 11000 at the date of today.

> My plan is to recharge the account again within a year using the Bouyges recharge. I'm hoping that will extend the account for another year.

yes.

> The website also does not show what the account expiration date is, as far as I can determine.

SMS 30 days and 6 days before the end of validity (phone + money loss)

> Question: Does anybody know for sure if recharging the account will extend the expiration date? The only thing that I've read says that you need something billable to extend the date. I'm not absolutely sure that I will be able to use the card for roaming while in the US

i did it X weeks ago. no money loss.
