Thanks for your interest in BSSCommerce Customer Attributes for Magento 2
For your question, we'd like to confirm that the module supports 8 different input types, including Text Field, Text Area, Date & Time, Yes/No, Multiple Select, Checkbox, Radio Button and Dropdown currently.
Regarding above fields, as I see it supports all fields except for user avatars. If you'd like to implement this feature, we would like to offer you our customization service to have the module fit in your own needs.
