I recommend you develop a website. I did this a few years ago. It provided an insight to me about website behaviour, design and cemented what I like and dislike when viewing other photographic sites. It is subjective and particular to me, but this is how I wish others to experience my images. I started with a pre-built site but soon migrated to my own site (read steep learning curve). This move was primarily cause I did not like the limitations on what I could do and restrictions on what couldn't do on the initial commercial site I was utilising.
My current site is:
https://www.craigmcgowanphotography.com/
On a technical aspect you need to secure a domain name. This includes ongoing costs to maintain ownership of the name. Plus ongoing maintenance of the site every few months. But more importantly I suggest, it allows you to display your imagery as you wish others to view it. You curate your site and is a landing place for anyone who may be interested is seeing your photography. This in itself for me is an interesting ongoing project on my site.
I am not a commercial photographer. In other words, photography is not my full time day job. But I have been pleasantly surprised with the amount of traffic it experiences. Much of it directed from my Instagram account, but also a percentage from non-social media searches. Every so often I receive enquiries that culminate in purchases for either prints, or digital file sales for particular publications/use. For me, this is nice recognition for my photographic efforts.
Now a few years old, I am currently rebuilding my site with what I've learnt and what I currently like in showcasing my imagery. I hope to have this completed and online by next month.
Good luck with your decision and hopefully, your newly established website.
