Thank you for your advice. I understand where you're coming from, however, I respectfully disagree (plus, in my case, your advice is not much applicable, since my knowledge and experience with Python and .NET ecosystems are not that much different - I still will need to master quite a lot of topics and aspects). If I would be debating which UI styling to use, which relational database to use or even which front-end framework to use, I would agree that it does not matter that much and should be based on existing knowledge and skill set. However, I strongly believe that spending enough time to select the best/optimal technology stack for the target product is worthwhile and will provide a high return on investment. You don't want to skimp on architectural decisions, since fixing the wrong ones will cost much time, money, effort and, sometimes, will even be outright impossible. Hence my deliberation.
