Good morning. Your questions indicate to me that you have become serious about doing photography. I offer my comment from that standpoint.
The camera brand or type comes second to knowing how to use any camera to produce worthy photographs.
So, I strongly recommend that you study and apply the fundamentals of image composition. Visit this website for guidance in this central aspect of doing photography:
https://www.adobe.com/creativecloud/photography/discover/photo-composition.htmlAttend a workshop or two to become familiar with camera operation as well. Doing so will help shorten the learning curve; after all, photography functions as a craft. We must learn its tools.
The concern for which brand of camera to buy and use opens the door to a big topic in the field of photography. Let me please suggest that you rent a camera that seems to suit your hand and eye. Hands-on experience may persuade you in a purchase. Let's face it: Photographers may select a camera in part from its ergonomics.
But this concern also presents a choice arising from the personal appeal of photography to your senses. Do you like black-and-white or color (or both) as the primary avenue of photography. Do you like landscapes or portraits? And so on. The field of photography covers a lot of ground. You may not know the answer to this paramount question of which way to go until you actually practice photography.
Try the informal approach while you learn more about photography: Take a lot of pictures. Learn from your failures and successes.
As to the choice of a DSLR or a mirrorless camera, let me please note that only a short time ago, the DSLR served as the latest advance in technology; now, the mirrorless camera pretends to wear the crown. Yet, consider that you and me and others cannot tell one from the other in the final product of either camera.
Of course, we now see the flashy Artificial Intelligence approach to doing photography. The sell-jobs for it have started. Do not fear this technologic advance. The basics of doing photography remain in place, as always.
As to which brand of camera to buy and use, I offer this guide. Consider the availability of gear and software behind and underlying the product. Canon leads ahead of all others.
Third-parties will naturally cater to this leader, offering a wider array of support. Nikon-lovers will find plenty of options, too.
Canon offers refurbished cameras at a cost lower than for new. I note that Canon scrutinizes these re-done cameras while undergoing cleaning, inspection, repair, and testing. In effect, the used camera performs as new-like, although another human being has taken pictures with it. I have bought and used refurbished photography gear from Canon with no problem. I also like SIGMA for its line of lenses compatible with Canon DSLRs. I own and use more than one SIGMA lens.
The hardest part of my comment here has to do with the intense sales bombardment urging photographers of all persuasions to buy this or that item, as if it represents the be-all and end-all of products under the sun.
Beware. Do your homework with a critical frame of mind. Read reviews. Avoid buying anything dependent solely on the shouting of an advertisement. Sleep on any purchase action. If really interested, rent to try before you buy.
In ending, I note the following extreme outlook for doing photography: You need only a single camera and a single lens for the practice of photography, or to learn it. You can practice photography with a point-and-shoot camera or your cellular telephone camera.
Despite non-stop, widespread advertisements showing photographers wearing backpacks, you really only need a camera bag with a sling strap to lug the camera with lens, along with, say, a spare battery and a lens-cleaning kit.
Note as well, that few photographers truly need a tripod for the practice of photography, no matter the bias and blandishments of manufacturers and their ads. Effective image stabilization subsystems have relegated the tripod to the fringe at best. I will grant that microphotography and certain other sub-fields require a tripod for best results.
I qualify my limited view by the obvious fact: Doing photography with artificial lighting (AKA flash lighting) does involve certain specialized gear. It brings up another side of photography.
Let us leave this side for later.

I am looking to buy a camera and I wanted to know three things first of all. What brand would you buy?
Second, what type would you buy i.e. mirror less or DSLR
And finally, would you ever buy a camera that has been refurbished?
