Macro lens choice 50mm or 70mm?

Hi,

I am looking for a macro lens for my daughter. She studies biology and likes and to photographs all the flower, bugs, insects etc. I would like to buy a suitable lens for that reason. Unfortunately macro photography is unknown to me and I don’t want to buy an inappropriate macro lens.

A have an Sony A7III and I am choosing between the:

Sony FE 50mm F2.8 Macro:

and

Sigma 70mm F2.8 DG Macro Art

https://www.dpreview.com/products/sigma/lenses/sigma_70_2p8_dg_macro_a

Which one would be more suitable for my daughter's needs. What role plays the different focal length of both lenses. Both are 1:1 lenses and I understand that with the 50mm I can (have to) get closer to the subject and with the 70 mm I don’t have to get that close but I cannot evaluate what is better for the praxis and if there are any other aspects I am not aware of.

What focal length do you think would be more useful 50mm or 70mm?

Please advise.

Jan
