It's fine as long as it's not all they are eating.
I did a mixture. I did BLW with DS1 but with DS2 he preferred to be spoon fed and I did loads more jars. I quite enjoyed it TBH!
So I did things like mushed up weetabix, baby porridge (unsweetened) but I also made him some purees of my own - whatever we were eating I'd hold a little bit back (from the night before) or whatever fruit I'd got that week, I'd stick in a little bowl, perhaps with some formula milk, cow's milk or water to loosen it, and mash it up with a fork. You can use a smoothie maker or blender to make it smoother if you want to but I found this texture was fine. I also did some standalone ones like carrots/peas/potato. Normally when I made something like this it would be enough for several meals so I got some little plastic pots to freeze them in like my own "jars". Sometimes I'd add a bit of extra potato or the porridge flakes just to smooth it out a bit and add some starch.
Microwave scrambled eggs are also easy and quick although probably he was a little bit older for that texture.
If you look at the ingredients you will find most fruit pouches or jars are 90% apple or pear and most of the savoury ones are 90% carrot or rice. So you are paying a lot for these fairly bland ingredients. They are good for convenience but it's also not a huge amount of effort to make a small amount that will do for 5-6 mealtimes when you're first starting out. I didn't bother with complicated Annabel Karmel recipes etc. I just used easy foods that we were already eating, supplemented with frozen/tinned/leftover veg, microwaved a potato to "bake" it then scraped out the inside to add, etc. Shredded cooked chicken, any mince dish in the slow cooker (makes it really soft) or flaked fish are also soft enough for a little baby to cope with in a puree/mash. And small amounts of things like tinned spaghetti or baked beans are fine when combined with other ingredients like potato so that the salt is "diluted" a bit. I made vegetable soups (for me) and took DS2's portion out before adding extra water so his was thicker. Then added salt/pepper to season mine a bit more.
The Ella's Kitchen are the worst for the "vegetable" ones which are 90% apple sauce
I also tended to avoid anything sweetened with juice because I wouldn't give him juice to drink at that age.
Lastly a pouch squeezed onto a spoon and fed bit by bit is OK - don't let your baby suck straight from the pouch as this is terrible for their teeth as well as being a bit more removed from the whole tasting/exploring experience. People often do it because the baby will suck more food down quickly or to make less mess, but it's not a good idea. The bonus of this is you can also close the pouch and save the rest of it for later.
This set was also great:

I used the masher loads to mash a small quantity of food, and still use it occasionally now he is 2 to make a toddler-sized portion of mashed potato or mash a single banana (which you can also do with a fork). The ice lollies were great for summer/teething (with water/expressed milk/fruit) and the pots are a great size for storing food in. I'd actually get the extra set of 6 more as the size is so convenient if you're used to jars and they stack.
