Man, I really adore both I Just Want to Freeload on Your Luck and Death is the Only Ending for the Villain. Recommendations? Hmmm... Let's see... After wracking my brain, I came up with two titles that should keep you busy for a while, assuming that you aren't already reading them. 

Have you given Isn’t Being A Wicked Woman Much Better? a read at all yet? (https://www.novelupdates.info/series/isnt-being-a-wicked-woman-much-better/) I find it to be right in the middle range between the two series that you mention in tone. The MC's personality is somewhat realistic in that she is hardworking but isn't a Mary Sue. The translation is excellent as well, which is to be expected from the folks uploading to Mythical Merries. 

I'd also recommend the quirky regressor cultivation series The Healer Demands payment. (https://www.novelupdates.info/series/the-healer-demands-payment/) At times, it reminds me of some of the characterisations in I Just Want to Freeload on Your Luck, but with more magic. The MC, Meng Qi, is just as fed up with how things worked out last time. However, there is a sense of pragmatism as well, because she realises that she is still bound to the rules of the universe in which she lives. My only complaint is that the translation could be a bit more polished, but is still quite an enjoyable read in spite of this. 

I'll let you know if I find anything else that comes close to those titles in tone or aesthetics. If you do check out the series above, let me know what you think of the recommendations so I can refine the recommendations for you in future.
