We are looking forward to developing a new application, we are exploring whether to stick with Firebird or try something else.

We aim to expand our business, and considering our past issues with Firebird, we are uncertain about continuing with it. Even if we are familiar with handling Firebird and the firewall, moving away from it would be a straightforward process. 

However, we are actively exploring alternatives. Currently, we mostly use it on the Windows platform, but I know it also works on Linux. Though we haven't utilized it on Linux yet.

I've tried various ones in the past, like Access, MySQL, Paradox, and more. But they're not used anymore.

I am evaluating MariaDB. It has better integration with Visual Studio.

I didn't evaluate other options. I found a recommendation for this solution online and decided to implement it.
