Image, maybe some tables. I've plopped a spreadsheet into Evernote once but a mini calculator will do.

I do use Evernote's business card scanner a lot but I'd rather just pay for a specialized business card scanner app.

Evernote does all this but it lags too much when trying to read from my phone.

At least for me, something important that could be considered "heavy duty" is the ability to read and write notes from both my phone and computer.
