It might be a bit more of a fiddle than the tape method but it's a reasonable approach. Masking tape can add to the cost of any jobs like this though.
I picked some up from county chemicals recently, different type might be more or less useful. Certainly the site itself is a goldmine for information about sealants.
Tbh, I just feel like expanding foam is asking for trouble and the prep time to avoid making a mess, paired with any cutting back just seems like it’ll be a total run around.
Those strips seem like a good combo of cost/efficacy/mess of job.
I wasn't recommending expanding foam. It's just a different type of caulk saver, it's flat not round. Since you need to cover it with some sort of caulk you'll probably want to use masking tape for that as well. I certainly do these days. I use a few other time savers from sealants online too.

The parent company is called county chemicals, would be a good front for a county lines operation.
