Consider a LWB
As a bent newbie concerned about traffic, you might want to consider a Long Wheelbase (LWB) model. With your feet relatively close to the ground, there will be fewer issues with frequent stop / starts in urban traffic. And they are readily available on Craigslist for $300 - $500. Look for Rans Stratus, Burley Koosah, EZ Sport AX, etc. Or visit AD Carson's Recycled Recumbent site.
Like you, I switched over to bents about 15 years ago due to injuries - and have never looked back. Good luck finding your first bent. It probably won't be your last 😀
