There are many who stays in Canada and go to work in US, whose client is not in border city. Some do travel monthly for few days to a week, have seen in some other threads.
As you wont be having visa for quite a while, it would be risky not to maintain status, which means that you should enter US every 30 days without fail(reason: Not every officer will ignore this 30 day rule and let you in and some officer might deny you based on rule). This way your status is current and you dont need visa to enter US(as long as uscis prints I94 while approving your petition).
Are you filing in premium or not?
FYI - Already uscis staff will go on furlough due to non-allocation of budget, still not certain but its a possibility. Also due to covid and possible budget cut hence prospects are not great in getting the work done fast from uscis.
