    The maximum max jobs per client is 99. 

    This is a theoretical limit. I have never seen any client being able to handle this amount of streams.

    I would personally start with 4, then try 6, then 8. Carefully monitor cpu and memory usage on the client as well as backup throughput after each increase.  Depending on resources, you will get to a point where jobs will be queued or where performance deteriorates. Stick to the value where you got best performance.

    Remember that Max jobs per Client is a global setting.
    You can customize per client in Host Properties -> Master -> Client Attributes.
    Add/select client name to customize.

Based on that tech note i guess the way to proceed it to not use the change journal (set via Host Properties of the client where you would have it set to use the archive bit)

That may be different if you are using Accelerator though as it will use the chnage journal if it is available

All of these however are dependant on whether the client itself actually has the change journal actually enabled

In view of the advice and what you want it would probably be best for you to have your multiple policies, incremental backups set to use the archive bit, use accelerator too but have the change jounal not enabled on the client itself
