I can't really offer any better advice than has already been given above. Don't equate SC with ED is all I'll add, both are very different experiences in a gameplay sense. SC is
very limited with few working or complete gameplay loops but can still be rewarding despite that. Mining is my particular thing, but I dabble in most things as and when the mood takes me. Star Citizen is also less solo player focused, it's way more engaging when played with others...even randoms from the live in game chat, there are always new guys looking to expand their experiences through teaming up with other players, new or not.
The longer term players will usually offer help in many forms...trying out ships, suggesting workarounds for common bugs, gifting credits to get you started or just flying along with you in your ship or theirs to share bounties, complete delivery missions or try out mining...anything. If you have any questions or encounter issues...just ask in the chat, it's very socially oriented compared to ED, especially through the live global chat. It has a very small play area comprising of only one system although there's still a fair bit to see and do.
Most of the gameplay is beset by interminable bugs, server instability and server/client desync...which has gone on for several patches now and getting worse rather than improving. This, more than anything else, will dictate what your experience will be like...
It's...different. Many of us like what Star Citizen has to offer with some of the things you mentioned, some don't. I like both games for very different reasons...that's OK too
