static home page with Radcliffe theme

Hello, love the look of this theme. I am very new to WordPress so this may well be a really stupid question, but I’m trying to set a static home page. I’ve taken the steps listed on help forums for this issue (made a ‘home’ page and a ‘posts’ page), went to Settings-Reading-and set to static home page, choosing home page. In the Appearance-Customize chose “Static Home Page” and chose “home”. But when I go to Pages-Edit and select home page, there’s no option in Page Attributes to select a home page template. Do you need to build a home page yourself? Or should there be a template, and if so, how do you access it? I’d love it to look like the version on Anders’ site (https://www.andersnoren.se/themes/radcliffe/) including having the posts show up with images as on his site. My site is https://www.artasartifact.com (it’s in very initial stage!). Thanks for any and all help.
