Bryan,
I’m glad that you found what you where looking for.
I must have missed the part about it being 100% Instapage when you said CMS I thought meant something on else with instapage I think of it as landing pages not a CMS
I want to help so you asked about Google search console how often you need to request google index your site.
First make sure
You should have 5 urls in Google search console
your domain, http://www. , http:// , https://www. & https://
you should not have to requests google index once you’re pages are in googles index. There is no time line to make you need to requests google index.
Use search consoles index system to see if you need to make a request and look for notifications
Times you should request google crawl when adding new unlinked pages , when making big changes to your site , whatever adding pages with out a xml sitemap or fixing problems / testing.
I want to help so as you said you’re going to be using Shopify.
Just before you go live running on Shopify in the future you should make a xml sitemap of the Instapage site
You can do it for free using https://www.screamingfrog.co.uk/seo-spider/
you’re running now name it /sitemap_ip.xml or /sitemap2.xml upload it to Shopify
& make sure it’s not the same name so it will work with your Shopify xml sitemap /sitemap.xml
submit the /sitemap._ip.xml to search console then add the Shopify /sitemap.xml
You can run multiple xml sitemaps as long as they are not overlapping
just remember never add non-200 page, 404s, 300sno flow , no index or redirects to a xml sitemap ScreamingFrog will ask if you want to when you’re making the sitemap.
Shopify will make its own xml sitemaps and and having the current site as a second xml sitemap will help to make sure your change to the site will not hurt the intipage par of the Shopify site

know adding a XML Sitemap is a smart move
I hope that was of help I’m so about miss what you meant.
respectfully,
Tom
