Recommended investment portfolio in https://standard.com/ (403b)

Hello!

I am trying to figure out which funds I should invest my 403b in at https://standard.com/. I have been using vanguard for a while so I’ve been doing 90% VTSAX and 10% VBTLX.

https://standard.com/ (StanCorp Financial Group, Inc.) does have VFIAX so I might choose that since I believe that would be the closest to VTSAX, but their bond options I am not sure about.

For reference here are some bond funds that standard.com has:

Thank you!
