Construct as a website not a good idea, since most of texts and images are rendered inside a canvas, therefore the content inside it, can't be indexed by engines, and also the content generated by your construct app/website it doesn't stay there, it's only generated when u turn on or load the app/visit the website so the crawling of robots doesn't happen when search engines wants to index your pages.
And for a website and SEO purpose/visibility on certain keywords, and content that is a must to have, always visible content, pages, images, etc.
If you want to build websites,i recommend learning this 4 languages, HTML5, CSS or CSS3, Javascript & Php.
Php nowadays is not really needed unless u want to do your own backend stuff to server etc... but if u just want to be able to install a wordpress environment and code stuff in it ... those 4 programming languages, or scripting languages should get u started. (if you get to understand javascript you don't really need php, you can work around php features with JS, but is good to have php skills)
And the beauty of this 4 languages? all u need is notepad, (but i do recommend visual studio code, it will help you tidy up things faster plus u can do complex stuff with it later on when ul need it).
There are other complimentary stuff that might help you for more complex features in your websites, like XML, Json file structuring etc... but those u will learn them by learning the 1st 4.
