The STM32F070RBT has Hardware Flow Control for RS485, with DEAT, DEDT and DEM bits in USART_CR1 and USART_CR3 registers.
How do we identify which series of ICs have these features easily? Is it a particular series or type? The STM32F4 IC we are currently using does not have this option however it is not highlighted as different on the datasheets.

You'd need to look at this historically - the RS485 features first appeared in 'F0/'F3.

F1,F2,F4 and L1 were designed before F0/F3

Thanks both. Can it be assumed that all F0/F3 UARTs have this feature do you know?

I don't know.
But in general: if it is important, don't "assume", check it, work through the datasheets.
