I'd definitely suggest going to open days and talking to people who study the different courses and discussing your previous experiences with course leads. It sounds like you might be a good candidate for a concept art course, too. These are generally digital art-focused courses with concept design for games and film in mind. Bear in mind this is a very competitive industry and you'll need to work hard and likely do work outside your course to succeed in the competitive market, but it sounds like it might be a good match for your interests.
I went and studied Game Art without prior 3D knowledge, but with a big interest in 3D! I had a great time in the end, so don't rule it out. It doesn't disqualify you by any means. There's some great simple tutorials to try stuff in Blender, too.
My course had 3D as it's main component but with modules in traditional technical drawing and digital art too.
And any good concept art course will also involve some 3D, it's a big part of the modern pipelines for creating concept art now. In fact, i'd really compel you to choose a concept art course that does have a 3D component - it adds an extra skill to your toolset and might make you more employable 🙂
