Since this flat topology will rely on ISL/LAG and STP there is no limit and requirements for the switches to be of the same model (shown in the topology section of the guide). Having a tiered topology is recommended to have better scalability.

    correct me if i am wrong but my understanding that in a tiered topology and for my access layer specifically - I would need to dual home every single access switch? Correct?

    It's not mandatory, it's good to have for better redundancy and throughput but the access switch can still work with only one uplink.

    Take a look into this post to answer the first question: Technical Tip: Cannot get more than 8 FortiSwitches managed on a FortiGate

    Regarding the second question, you should not have any problem mixing models on the same ring as long as the STP is well configured.
