I think you need to define your goal more clearly. You say you want a budget, but different people mean different things by that word.
Do you mean you want to assign yourself spending limits in various categories each month, and then track expenses to make sure you stick to those limits? Because if that's what you want, then by definition you *have* to categorize your expenses. However, you don't have to distinguish between paypal, venmo, cash, credit card, etc. unless you also want to track the balances in each of your accounts. If you do it that way, you could use a plain spreadsheet or even pencil and paper. For many years, we just hung a clipboard with a pad or ledger paper on the kitchen wall. Each spending category had a column, and every day we'd write down what we spent that day in the appropriate column. Easy peasy.
However, this is an area where you get more information if you put more work into it. You could minimize your workload by having a very few categories: Housing, food, transportation, clothes, work necessities, entertainment. But then you wouldn't get the detailed information (e.g. how much do we spend on groceries vs. eating out? how much is my car costing in repairs each year?) that might help you with future spending decisions.
Also, there is a bit of a trade-off between ease of making entries and ease of getting info out/analysing it. Our paper-and-pencil method made it super easy to record expenses, but it was a bit of work to do all the addition at the end of the month, transfer totals to a yearly sheet, recalculate monthly averages, etc. If we'd used a spreadsheet, the barrier to making entries would be higher but it would be easier to feed the data into sum and average functions. With a smartphone app, you can get easy entry combined with easy analysis, but you have to spend the time to learn the app.
