My suggestion would be Apistan (based on my Maine experience) especially
since you have not treated for some time and last treated with
Cumophose. But I bow to others in Yoon's area and with local experience.

My guess, and it is just that, is that Apistan will be effective and
probably more so than Cumophose especially after three years of not
treating. (One test for Cumophose resistance is an Apistan strip to see
mite drop. Even when Varroa is resistant to both you get good mite drop
with Apistan but not with Cumophose.)

Oxalic Acid would be a good alternate treatment but is not an authorized
treatment in the US, and I have no idea how well it works with large
Varroa counts. It does work well (95%) as a normal fall treatment in
tests in Europe, where it is legal in several countries.
