Amazon ElastiCache Memcached Free Tier

I recently attempted to create a Amazon ElastiCache instance using (Memcached) and was following the instructions on here: https://aws.amazon.com/elasticache/memcached/wordpress-with-memcached/

In the very first step it shows that there is a setting for the "Node type" and explains that it must be set to cache.t2.micro to ensure that it is eligible for the AWS Free Tier.

However, when you actually go to create one (December 2023), there is a completely different configuration settings section and there is no mention of the AWS Free Tier. I'm assuming the documentation is just out of date, but reading around, it looks like I am now required to know the maximum usage limits for memory and compute settings and set them manually. Is this correct?

Create Memcahed cache:

Create Memcahed cache - Default settings:

Create Memcahed cache - Default settings - Customize default settings - Maximum usage limits:

The pricing page https://aws.amazon.com/elasticache/pricing/ also tells you to use the cache.t2.micro or cache.t3.micro node type. Later on in this page it lists the standard cache node specs. Are we expected to look up the memory from this table and use it on the maximum usage limits when configuring the elasticache instance?

Perhaps am I missing something obvious? Thanks for any input
