Modern hiring practices are too rigid and filter-friendly for you to likely appear as a strong candidate based on the fact you have good accounting experience on top of your growing software skills.
What will really help you though, is having friends who work at a bank in the software departments. It's almost always who you know in this world. You need to network, network, network!
I don't say this to blow my own trumpet, only to say that the non-engineering leadership at the company in question were very invested in the product details and making sure I understood basic accounting principles.
That said, I went from that role to working in a billing system that was originally built by a team where leadership weren't invested in the details. The result was a lot of issues and frustration from Finance leadership. Storing monetary values in float was not the biggest issue, either.
That being said, maybe branch out of just looking at accounting/bookkeeping and market yourself as "I know how money works in software systems." Your skills are extremely transferrable and knowing the Finance expectations will make it easier to make good design choices further upstream.
