Hi TAnne1 -
(This is not professional advice - do your own research, satisfy yourself, and go from there.)
FBAR filing is only required when the
aggregate value of
all foreign financial accounts (your own or an AC for which you have signature authority) exceeds $10,000 at any point in time during the year. It can kick in in funny ways - transferring money from 1 UK account to another can make it appear that you have >$10K for a nano-second on a given day, when in fact you don't. For example - you have $6K in an account, but decide to open account #2, and transfer $5K - there is a moment in time when AC #1 says $6K and AC #2 says $5K....and that means filing a FBAR. Seems silly (and it is), but that's one simple explanation for the 'when do I need to file?' rule.
If your foreign accounts (including ISA) don't exceed the $10K amount, then you don't need to worry about it.
You need to re-think how you file your US tax return, and part of that will be based on your husband's US status, and whether he still holds a green card (or has given it up). Typically, if the UK spouse has NO income from the USA (and that includes interest on a joint AC), does NOT have a green card, and is NOT a US resident, then your filing status would be 'married filing separately' as it's usually not to your advantage to include his income. If you meet the requirements, you can claim an exemption for him, which is made easier since he has an ITIN.
The UKVI will not care how you file a US tax return, or even whether you do or not. That's not a document they ask for or would even understand. Don't worry about that w/r/t the future FLR(M) application.
If your husband is NOT subject to US filing requirements and you have no income or your income is
below the filing threshold, you don't need to file a US return, though it may be to your advantage to do so.
A couple of the tax professionals will likely jump in here and quote a lot of stuff, some of which will sound really scary. There's various rules/scenarios for green card holders that are no longer resident aliens that might apply to your situation; read and research and go from there. Don't over think everything, but don't put it off until next April either

. Also, don't assume that you need to pay for dual qualified tax preparation services. Most of us have situations that don't require that expenditure.
